The easiest way to do it is with old technology.  I debounced my bug by 
having it key a Radio Shack 12v reed relay.  There is a 10 uf capacitor 
accross the relay coil, or otherwise it is fast enough to follow the bounce!

The bug relay (as well as an opto-isolator hooked to the parallel port 
of my computer for contest loggers) are connected accross the paddles 
with a pair of Schottky (sp?) diodes.  The K2 works great with the 
paddles, the bug, or the computer with no changes needed.
