HOW TO: Setting up rails for "shared hosting" on a dedicated box. . .?

[Michael Williams]

Hi All,

A partner and I recently purchased a dedicated FreeBSD box.  We're  
currently using Plesk (blech!) to manage client domains and such.   
I'm curious though as to what the best (most manageable) setup/ 
configuration is for supporting Rails for each of our clients.   
Basically we want to be our own Shared Hosting Rails Provider (for  
lack of a more appropriate phrase) and need to figure out the best  
server configuration.  Just a bit of an FYI, everything is already  
running on Apache2 so I'd need to share Apache2 among all programs  
(e.g. svn, rails, etc);  as opposed to splitting tasks between Apache  
and Apache2.

If you could point me in the right direction it would be most  
appreciated.

Regards,
Michael
