So according to the wiki the EXT port has the 'lost' USB Host functionality on it.
Several things need to be done:
1. Compile Kernel with MMSP2 USB modules (or is it all monolithic now?)
2. Test USB Host pins for responce, probably will need some kind of logic analyiser.
3. Determine what else needs to be done (if anything) to enable USB Host devices to work thru the EXT port.
4. Build a USB/TV/Serial cable from one of those:

(use an external 5V adaptor)
5. Test with various devices. (USB Hubs/ Keyboards/Mice/Joysticks/Toasters/WiFi/Ethernet/HDrives/ect...)
6. Sell and make $$$.
An alternate portable version should also be considered.
Where the USB Host ports would be on the top of the adaptor, so a USB-WiFi sticking out would not get in the way of anything. The adaptor should be as small as possible.
It would need either a really small internal rechargeable battery or a DC-DC step-up chip.
(an extra capacitor or inductor depending on the type, should be able to cram it all in a square inch)
The portable adaptor would be held on with Velcro and that would be adheared to the battery pack/ back of the system.
A 90° Degree EXT plug would also be a good idea.
