My home office consists of a Mac with Tiger OS X (which is main working unit, BTW) and 3 PCs, all connected by a LAN network (all Windows XP SP2). I have a huge amount of data (mainly research papers, data, PDFs, drafts) I would like to be synchronized across the network. Is there any good solution?

.Mac (dot mac).... (specifically iDisk on .Mac)

it works on PC as well as Mac.

here's a link to the .mac page with info on this:

Yep, you can use the iDisk with Windows XP.

I am talking about 3 GB of data.. and I have very slow DSL, so I prefer a sort of LAN decision, rather than synchronization through Internet with my slow DSL
