One problem with remote backup, and this applies to any "cloud" or other internet-based option, is that most residential 
internet services have outbound rates measured in bits per fortnight. You have to go to a business type account to get 
anything even close to 1Mbps. outbound, and that is dog slow by today's standards.

There are in fact tons of "media players" available now, some for well under $100. I think some BR players can also play 
back from USB storage. Netflix streaming is starting to get more people aware of and interested in such devices, but you 
have to be careful which one you buy. For example, many can't handle MKV files, or DTS audio.
