ah ha... I didn't think about it like that. I personally use a Mac mini as my FOH server, with VNC, and do the same as you described, so that would actualy be a smart way to do it.
i've never used chronosync, but that looks like a great tool, I think i'm going to download it now.
In your thinking (which is where I wasn't) that is a magnificent idea. Especially since I've now started bringing my G5 with me for content changes, I could simply run it on that FOH.

question: how fast does chronosync work when running 4 servers? decent?
