How about this, A remotely located billing/client/affiliate manager

You log in via the site Add products, choose credit card procesor, ect.. then it makes a link like www.hostingmanager.com/buy?adminid=you&product=productID

then it takes them through the process order forms ect.. and redirects back to you're site

Also an affiliate manager so you could add them and they could sell you're products and get a commision or set price so the link could be something such as

hostingmanager.com/buy?adminid=you&affil=them&prod=id

and we could write just a small script that you could put on you're server called order.php and it would hide our site and just have you'res.

What do you think? Suggestions? Crap idea?

I think most hosts would rather have all the script reside on their server.

Isn't that what Ubersmith does?

Ubersmith allows you the option of having it hosted with them or on your own server.

Btw, as a side note, I just acquired an Ubersmith license and so far from what I can tell.. it's great.
