[Ruby] rails question

[Raymond Forbes]

Hello,

I am not entirely sure how to even ask this question so hopefully that 
helps show my rails ignorance. 

so, i have a website hosted on a server with multiple vhosts.  we use 
Apache web server.  i want to create a calendar application and deploy 
it to my server.  I am not entirely sure how to do that.  I have rails 
apps using various single install solutions but that doesn't really work 
here.  So I guess my question is, how do you deploy a rails app to a 
multiple vhost server?

hopefully that makes sense.

thanks!
