Just to add to the confusion - but interesting.
At our community radio station we have a piece of gadgetry called a PogoPlug. This is basically an external hard drive linked to a computer which in turn is linked to one of our routers - we have two, one used solely for streaming radio ( www.reading4u.co.uk ) and the other for general office stuff. The PogoPlug requires its own e-mail address and password and any of us with these can access anything we put on it from anywhere. Very useful for audio files, forms etc.

All in all a handy piece of kit.
