We're looking at hooking up 48 small embedded systems with 10/100 Ethernet ports to an Ethernet switch and then have that switch talk to a server upstream via a faster connection. I have a couple of questions about that scenario:

What kind of upstream connection is best (fiber, other?)
Would it be reasonable to download 1GB/hour from each of the 48 systems concurrently? We'd be using some kind of TCP based protocol of our own design.

Thanks, Andrew
