Maybe 'rvm' is not a critical requirement for this (?)
I think the requirement is to have:
* either the different versions of the gems installed
* or to vendor the rails versions
Without using rvm (just the 1.8.7 system ruby of Ubuntu 10.04),
I was trivially able to run 3.0.3 and 2.3.2 (Uh) in parallel ...
pet...@asus:~/ra/apps/trials$ rails _2.3.2_ rails_2_3_x
create
create app/controllers
...
pet...@asus:~/ra/apps/trials$ rails new rails_3_0_x
create
create README
...
pet...@asus:~/ra/apps/trials$ ls -l | egrep 'rails_'
drwxr-xr-x 13 peterv peterv 4096 2010-12-22 22:42 rails_2_3_x
drwxr-xr-x 13 peterv peterv 4096 2010-12-22 22:43 rails_3_0_x

Running the web servers in parallel:

^CExiting
In a different console terminal:
pet...@asus:~/ra/apps/trials/rails_3_0_x$ rails s -p 3001
=> Booting WEBrick
=> Rails 3.0.3 application starting in development on
http://0.0.0.0:3001

Or did I overlook something ?
HTH,
