How are the the PyPy developers supporting themselves? Are they being paid salaries from the project, which (if I understand correctly) is currently being funded as an EU research project?
Obviously the PyPy code will deliver vastly more than $10k of value to the world. Keep up the good work.
Some of us (myself included) are volunteers. Others have it as their day job, by virtue of funding from the German and Swedish government. These funds will probably be used to allow devs to work on PyPy full time, as well as to bring devs to sprints.
