I found nice toy called the Draytek Vigor 2200USB.
This is a ADSL Router,4 port ethernet switch and USB Master.
It came out last year and a quick search found a price of £175.
If it would be possible to get it to work with the empeg it would expand the possibilities of the world of the empeg.
Please read the below link for more information or search the net.

Can I add other USB peripherals ?
Not currently. It is intended in due course to support various other peripherals. The schedule or types has not been announced yet, but this might include any USB device such as webcams, printers, analogue modems, ISDN TAs, VOIP devices, bluetooth or Ethernet802.11b adaptors etc.
