We have used github and dropbox in the past. As far as getting multiple people working on the same code it eventually goes back to the one computer 5 or so kids crowded around because they normally flock to the main programmer.

As for code retention and version control It took 4 years to get a good system developed that the students actually followed. We just have multiple copies of code in at least 3 different places.
