Are RH CGI the way to go in order to reduce CPU consumption and bandwidth? Especially for a site nearing a million hits per month. What are the inconvenients of remotely hosted CGI compared to self-hosting CGI? Is it thinkable to have a dedicated shared hosting plan to "house" CGI away from the main server.

The main issue is not remotely hosting CGI. If you have that much traffic, you may want to separate the DB from the main web server.

If you do remotely host the CGI, you probably need a dedicated server. Most shared hosting provider will kick you out if you use too much CPU, although they will happily charge you for the bandwidth/transfer.

If your site makes heavy use of CGI, I seriously doubt you are going to find a share provider who will let you host a cgi-only site for more than a couple of days :). You would simply be eating up too muc CPU on their server. Your best bet is to get a dedicated server, and run the the scripts on that.
