Glenn, RVM doesnt hide anything from you, in fact it sets up your environment to "just work" with the selected ruby. Below is my output from "rvm info". You can see it sets the PATH properly, etc. If you start your IDE from the same shell, it should find ruby and your gemset (if it uses the proper ENV vars to do it).
The RVM site also has loads of info on getting Passenger to work with RVM. There are some rough edges, but it works.
