Hello!
ednet[1] and RaidSonic[2] sell boxes that can forward USB
ports over via the Linux USB/IP[3] system.

From the web site the transfer rate of these boxes is 10/100Mb/s.
So theoretically it should transfer a maximum of 12.5MByte/sec which
is far below the required 32Mbyte/sec of USRP1.
2 Points:
1) USRP is known to be able to transfer maximum 32 MByte/sec, but you do
not need to run at this data rate.
2) USB/IP is not limited to this boxes. You can forward USB connections
from a Linux box to any other Linux box. The mentioned boxes just happen
to do this as their main task. You could do USB over IP forwarding via
Gigabit Ethernet, that would give you about 100MByte raw transfer rate,
which should be sufficient for maximum USRP data rates.
Just wanted to know if anyone used something like this already. I could
get hold of one Raidsonic part, maybe I'll give it a try. I'm not shure
if USB/IP supports the transfer modes that the USRP uses.
