This is an interesting idea, but historically it has been difficult to adapt software to run effectivelly on a loosely connected parallel processing system like this. Only certain kinds of projects are suitable, and the technical hurdles can be difficult to overcome.
A cautionary tale is Thomas Ray's "Network Tierra" project. Ray got a lot of publicity in the mid 90s for his Tierra alife simulation, which seemed to evolve various forms of artificial life forms, including parasites, predators, and other complex ecological entities. He got the idea to extend it to run on a network of personal computers similar to what Spike is suggesting. The computers would have different properties (some would have more run time or memory than others, for example) and life forms could migrate from system to system. The idea was that the variation in environments would be an additional engine for evolution.
However, the project got bogged down in technical problems (i.e. bugs). http://www.hip.atr.co.jp/~ray/tierra/tierra.html describes the current status, but it hasn't been updated for a year.
Ray is now stuck teaching a "computer programming for non programmers" class, http://faculty-staff.ou.edu/R/Thomas.S.Ray-1.Jr/Zoo5970/zoo.html, at the University of Oklahoma. Had Network Tierra worked he'd probably be a household name (again).

Can anyone suggest a more Extropian project? Finding primes is pointless, and the SETI thing seems badly managed and inherently unlikely to succeed. Many of us see nanotech or AI as the paths to the singularity, and perhaps some bottlenecks in these fields are due to lack of computing resources. However it is necessary to identify a problem which can be solved on a loosely coupled network where communication costs are very high.

As in, "don't cross the beams" bad?
