I guess you have to make sure it is high bandwidth. If you want to stream over a wireless connection you have to make sure it's a good connection and that it is of high enough bitrate otherwise you end up with a choppy playback situation like my friend had with his home cinema setup.
You can't really use one of these to store files you are working on that tend to be large in nature, for instance networking and music production are a bit of a no, that's something that needs to be on your local HD.
Any sort of streaming activity though, that should be fine. So your music and film collection.
yeah this is pretty much exactly what we need to do.
if i can't stream films off it well enough i dont think it'd be hassle to copy them over before we watch them.
