Yes, I think synergy as the word is often overused in marketing-type appliations, but [Daniel] pointed me to Synergy which is an open-source keyboard/mouse/clipboard sharing program.

"Big deal"™ you say? It's not. This gives me the ability to use one keyboard and mouse between my desktop and laptop, and it doesn't matter than my desktop may be linux or Windows (depending on work or home) and my laptop is linux. It's very slick.

Pair this with arpdetect and a I can pair my laptop up with the server running at work or at home when I connect my laptop to the network. Sorry, but this happens to be a really Cool Thing™ to me.
