It has been asked before, yes.

The easiest way to do it is to just copy your userdata over from one build to the other, though this assumes that the paths used on both machines are the same (i.e. the media files are shared off a remote share on both machines etc.) and that the versions of XBMC used are in sync (at least as far as the versions of the database files are concerned).

There's a couple of alternatives to this:

1. Do all updating on the one machine, then just export your library to individual files. That way, all the information is kept next to your media files, and so scanning the library is very fast.

2. Use upnp to share your library on one machine to the other, though this isn't quite as rich as the local library experience as yet.
