Potentially. Read operations, I wouldn't expect to be a big problem, but commit operations need to atomic, and the software wasn't *written* to behave well with network mounted back end filesystems across multiple servers. So I wouldn't know, off hand, what phase delays between two front ends writing revisions at the same time might create for genuine adventures on the back end. If you need 3 front ends, you might really consider Wandisco's commercial package, which is designed for multiple front end use.
