A while back I posted about Mango Lassi and how awesome it was compared to synergy. I still think it is awesome, but every now and then something would freak it out and cause the association between machines to drop. I’ve fixed at least one cause of that problem now and published it in a git repo here: http://www.snorp.net/git/mango-lassi.git/
BTW, thanks for all of the great comments on the NAS situation. I’m looking at several of the options mentioned there along with a couple others. I think I’ve ruled out rolling my own, though, as I don’t want yet another linux box to maintain.
