I've been working with Marc and Salim with Webenabled and they have offered to provide us a free-of-charge VPS for Node, Mongo and Symfony testing.
We get to help out a great company that has been a sponsor of our past Drupalcamps and they get real-world testing of some new services they are trying to implement.
If anyone would like to join in, contact me. We would like to get at least twenty or so people together to work on it.
(They might even pitch in some free hosting for our efforts!)
