There's certainly transfer that will happen. Lots of the people involved are active in their respective non-OLPC communities. One of the things that's been mentioned most is performance work, particularly getting applications to just quiet down, and keeping them from waking up periodically. Since the laptop is supposed to go into suspend fairly quickly, and come out quite quickly as well, we don't want the laptop to wake up because some application or library is polling for something to happen.
I'm sure other things will come out of this as well.
