In this scenario, I'll wait to get an other VPS because 2 mongrel 
instances are taking more ram than the rest of the server. In the event 
of high load my VPS will start killing any process because doesn't have 
swap space.

What specs you would request for a ruby server (maybe just mongrel 
cluster and mysql listening to the prior VPS)

So, a shared server is not the best approach for ruby (or getting the 
same problems of PHP). Having 100 accounts with the corresponding 
instance would be problematic.
