Zinc wraps sbt's incremental compiler as a command-line tool and build daemon, and provides an API for other build tools like Maven, Gradle, Buildr, and Pants to integrate with. sbt already has everything that zinc has.

Other than the speed, it should behave exactly as a local build. No sharing of file system would be necessary; the interaction would happen simply via a network socket of some sort.
Yes, the idea of a distributed sbt that compiles in parallel across several machines has been discussed before. It could use some kind of general purpose distributed task engine. There has been some work in this area, and in distributed testing.
Your project, however, would need to have multiple subprojects that can be compiled in parallel for the work to be distributed. I don't how simple you mean, but I don't think a simple project would see much benefit, given the overhead of transferring files and less opportunities to parallelise.
Tools like rsync and ssh will get you a long way towards working across machines.
Cheers,
Peter
