The Apache Software Foundation is participating in Google Summer of Code 2013 and I'm going to join as the mentor of the Apache ManifoldCF proposals.
Each student involved in the program earns $5000 USD for working during the summer on an Open Source project. Each organization involved to mentor projects earns $500 USD per mentored student.
Actually we have two students interested in implementing the Email Connector, this specific case is allowed by the program but only if students will work individually on the same proposal.
This is a good opportunity to create a some kind of competition for bringing quality, fun and motivation to the job. They also will have the opportunity to work on a big Open Source project for the first time and become a contributor!
