carlgt1: the problem I've found with these cards is they're pretty damn slow, so transferring 16GB would probably take at best close to an hour? I mean say you can get 50 mbps (6.25megaBYTES per second) out of the fastest '.11n' network, that's 2560 seconds for 16MB (and typically you'd probably get 1MB/sec rates not 6+).
