Good rule of thumb there Don. One thing I hate to see (and hear) is two (or three) acoustic guitars playing the exact same rhythm part, same chord inversions and everything. I mean, what's the point?

Capoes are a nuisance though. If you have a guitarist who knows a bit about mandolin, but don't happen to have a mandolin in the group, its easy to fake a mandolin chop, tremolo etc on the upper ranges of the guitar.
