I'd like to use AeroFS as Windows Live Mesh is going away. I'm a heavy user of the PC-PC sync functionality and there's nothing similar available on the market.
BUT, AeroFS requires Java. So, in your opinionation is it worth it? I don't wear a tin foil hat, but Java is just a mess these days.
I've been searching for a while for a free alternative but haven't found something that works as well as Windows Live Mesh, but open to suggestions.
