I would take a risk and say that there is no interest but a need or even
demand of bringing a usable farm to FOSS4G developers.
The distributed nature of FOSS development requires larger
teams to stick to principles of "Continuous Integration"  because
it is crucial to keep work moving smoothly, with assurance of
decent quality of final product that makes all team members happy
and motivated to move forward, stay with in the team project and
support community. All these aspects are crucial to make a project
healthy and sustainable, so successful.
Without an efficient and reliable development infrastructure, it's
really hard to achieve these goals.
Many of big & healthy projects like Boost C++ Libraries, GCC,
PostgreSQL have used compile farms, distributed
regression test jobs, etc. We (OSGeo) have found Buildbot very helpful
once we've got used to use it.
So, for myself personally, no question about benefits of such solution.
The only problem I see is that we need more machines that are
connected "24/7" to make the whole solution usable and powerful
enough to serve all our projects.

Yes, but this is a technical issue that can be solved by "investigate,
learn and solve" approach, IMHO.

Yes, as soon as my Mac Pro is plugged in.

Thus, you may want to plug it into our Buildbot or equivalent for Java
(I apologise Java camp for my ignorance, but I don't know if OSGeo has
anything setup in that area, I only know Buildbot that serves C/C++ camp).
