I was going to diss all the other KM's.. (and maybe I should) but I do plan to have a nice snappy KM out in a couple of weeks (unless something goes seriously wrong:P) designed to work with keyclone, but I do not plan to offer mouse broadcasting - the Shockbeta modded Multibox is the only KM program that does that, but it's built in debug mode, so a bit slow, and jumps desktops :P. Otherwise, it's Multiplicity, Synergy (awful) or Kavoom.
