No, you can't live there, alas Jonathan. But if you could figure out how to work 24x7... : ) - Tim Rowe

Sync is hard, but it is not impossible. In the early days of Blackberries, when they were pretty much exclusively used by Microsoft Exchange users, the fact that Blackberries synced with mail servers better than anything else was their chief differentiator. For syncing files, my favorite sync platform right now is the product formerly known as FolderShare (now Windows Live Sync). It it peer to peer, free, Mac/Win friendly, and, as far as I can tell, it is perfect.
