Hi
I'm already using Mesh to sync favorites - it's very easy if you're using a browser which stores them in a folder like IE. Just map the favorites folder to Mesh.
ON the second (or third ..) computer, map the folder to the local favorites. It works great!
The only thing i'd like is that when viewing the Live Desktop, it would be nice to be able to double click on the synchronized favorites and open up the web pages, but apart from that, it's all good.
I think with the desktop, it's possible too - afterall, it's just stored as a folder somewhere in your profile. Well, that's the icons and anything stored in it. It wouldn't be much good for backgrounds, cursors etc. I'd be slightly concerned on the update speed though - sometimes when I log in, it takes a few minutes before changes are sychronized. Perhaps there could be a folder you specify as 'high priority' so that changes to that get synchronized before your other shared folders.
