Sync It Up...

So this issue has bugged me for a while and I never got around to sorting it out for myself.

I have multiple machines at home (Mac & PCs) on which I want to have the same files.
My primary option is a NAS box, but the tree hugging hippy in me feels bad about leaving it running 24x7 (it may be only 25W, but its 25W more than I really need to run).
Of course with a NAS box you just ensure you're always updating the NAS based file rather than a locally based one.
However, the downside to that is that you can't really take the files out and about when you go without sorting out some sort of sync program for when you get back home.

What I stumbled across last night (whilst reading some obscure technology post) was that Microsoft have introduced "Windows Live Sync" (albeit fairly quietly I think)....and the best news is that they've made a Mac client as well! (No sign of Linux unfortunately).

Essentially you run the client on the multiple machines you want to share across and log in using your Hotmail/Live account. You use their web interface to manage the sync'd directories on the specified machines (you can also 'share' directories with other people).
The software then ensures that you have the latest version of the files (in specified directories) on your multiple machines.
I've only done initial tests on this, but so far I'm quite impressed - especially considering its free!

So for anyone struggling with managing files across multiple PCs/Macs then this might be worth looking at.
