Using the same nameservers with two hosting accounts, possible?
I have a shared cPanel account and a VPS account with cPanel.
I'd like to put my main business website on the shared account.
I'd like to put my customer's website on the VPS account.
How do I go about using the same nameservers for both accounts?
Ideally, for extra protection, I'd like to host my main site on a different server in a different data center. This way, if my VPS goes down, my customers can still contact me.
Now would the best route be a DNS cluster or should I just make multiple name servers (ns1/ns2/ns3/ns4)?

You could just use the VPS for all DNS (even for your domain) which would allow you to use the same nameservers for both. The downside is that if the VPS is down, so will the DNS for your primary domain even if the server itself is online.

You can use clustered DNS.

why not just use different nameservers for the one special site. (your main business site).

WHU-Mike;
You may want to look at 3rd party DNS. In any case http://freedns.afraid.org/ may provide some free education.

You can buy an inexpensive VPS to use as a name server in addition to your existing VPS, and install cPanel's free "DNSONLY" product on it. I finally got my BuyVM 128/256 $15 per year VPS to install DNSONLY, so I'm doing this now.
cPanel will easily create a "cluster", syncing the main VPS (hosting your NS1 nameserver, for instance) and the inexpensive VPS (hosting NS2). You can create zone records in WHM on your main VPS without creating accounts for the domains, so you create a zone and an A record that points to any IP address you're using. Including for your account on a shared server, your accounts on your main VPS, or accounts on other servers.
I'm currently doing this with my main VPS, and the BuyVM $15 a year VPS. Zone files have A records pointing to one of three servers, my main VPS, my BuyVM VPS and a test VPS I have at Burst.net.
It gives you redundancy in case one of the servers is down (e.g., email is queued instead of bounced), and allows you to change accounts to a different server after a move by editing the A records in WHM (instead of relying on customers changing name servers at their registrar).

Sure, short of having a secondary system that hosts the DNS as well (i.e. a DNS cluster or DNS mirror) you're going to have a single point of failure for DNS. It's actually not that uncommon. For example, last I checked, Hostgator hosts all nameservers on the same server as the webserver without any clustering. So their NS are ns1000,1001,1002,10003, etc... for servers 500, 501, etc... Now those may not actually line up but the point is that they're not running a huge cluster or anything special and the DNS for each server has that server as a SPOF for the DNS for the hosted domains.

No. You set up the main VPS as hosting one name server record, we'll say "ns1" in this case, and "ns2" will be hosted on your small, inexpensive DNS. You don't have a single point of failure. If one VPS goes down, the identical records on the other VPS will respond to requests.
DNS queries do not go "in order", and either server could be queried first. If that name server does not respond, the request goes to the other name server of record.
If your main VPS is down, what is the advantage of having a second name server pointing to that non-functional IP address? The advantage is in the type of response sent back to the requester. Instead of being analogous to "sorry, that site doesn't exist", the message is "the site should be there; they must be temporarily down."
Email sent to a site that has a single point of failure in its DNS is simply bounced ... returned to sender, no forwarding address. Email sent to a site that has a valid DNS pointing to it is held for delivery later. And while the sending server determines how long the email is held for delivery, typical times are 4 to 48 hours.
For a business, instead of having your email bounced back to the customer with a message that the email address doesn't exist, it is held for delivery. If it isn't delivered in a set number of hours, the customer gets a notice that their email is being delayed, and will be delivered later. That's much better than the customer thinking you have gone out of business because your site, and your email, has disappeared as if it never existed.
An alternate method is to use a third-party external DNS that provides the same sort of functionality.

Yes you can try the clustered DNS.
