I have been looking on the wiki and either the information isn't there, or I haven't managed to hit on the correct search term

My Apologies if the latter...
I was wondering about removable media directors / players. My idea is that you could load something on a laptop which allowed media to be uploaded / synced and taken away for watching / listening to remotely. I work away from home and would like to be able to take my fave. shows with me to watch on the plane or in my hotel. When I return, I could simply re-sync. I can also see an application for fitting such a system in a car to keep the little ones occupied during a long journey ("Dad, are we theeeeere yet?" as we pull out of the drive.) perhaps a car-computer with a wireless link which sync's automatically when the car is parked on the drive....
On a releted topic, I have an iPod touch and would love to be able to sync it to my MCE library. Kind of an MCE version of iTunes, I guess. I am aware there are other MP3 / MP4 players out there which may also benefit from similar functionality.
If this type of thing doesn't exist, I'll repost (or request the topic is moved) to "Feature requests & roadmap"
