I've a primary desktop pc with Linux/Windows on it and a secondary Mac mini with OS X and Windows, one monitor each.
I'd like to share keyboard and mouse from primary to secondary, have already tried Synergy but it currently lack international support, so on my Italian keyboard some main key, like the space bar, doesn't work correctly (already filled an issue long time ago).
Lately I've seen some promising hardware usb km switch device (try google for 2 port usb km switch) even with clipboard sharing support (wireless or with cable doesn't really matter to me) but any I've seen had some limitation, like only english layout keyboard support or partial support for some of the OS (Linux can't be used as server).
I'd like to know if someone is successfully using some hardware km switch with Linux/Windows as server and OS X/Windows as client, with international keyboard layout support (and obviously eventually what is this device).
(I tagged the question kvm-switch but would be km-switch which doesn't exist and I can't create)
