Windows (Live) Photogallery is much better in this regard, as it indexes the files but keep the files were the are stored. Also all metadata changes are stored back to the file itself. The same goes for Windows Explorer and OSX Finder+Spotlight.

I have my LR catalog on Dropbox, and all of my photos on an AFS share on FreeNAS, which isn't always available (I have a VPN to home, but it depends on the speed of my connectivity). I generate 1:1 previews and don't expire them, so I can use LR with the same settings and edits on both my iMac and MBP. The only issue is having LR running on both, at once.

Lightroom supports sidecar (xml) changes, or syncing metadata to the files. Your choice.
