It's things like this video on upnp http://base-art.net/Articles/94/ that make me want to get my hands on a n800/n810 right now. Of course I'd have to expose libferris as a upnp server for the path to the dark side to be complete...
Searching using ID3 / Annodex metadata and having your files served up my libferris... eases the pain. If only I could have made it to LCA and scored one of the n810s they were giving away... ah the waiting.
