Benson, I'll take a look at the "spider cable" and let you know, it should be fairly straight forward to pop it open (it's just plastic tabs, but you never know, it could be glued). Interesting idea about re-jigging it, I'll do some poking around inside and see what I can come up with and let you know.
(Edit: Photos of the spider cable opened... top and bottom... there are just two screws under the label that keep it closed. No 5 wires for the mini B and no idea about adding an external power source, but at least it gives you some ideas as to what's inside there)


I'll also look into the other bits and pieces that you had listed there; I'm setting up a partnership for distribution of Solio Solar/Lith-ion chargers, which in my opinion are awesome for use with the tablets (others have also reported) so that's what I'm leaning towards for an extra battery/power injector solution. The nice thing about the Solios is that they have interchangable tips (comes with the one for the tablets btw) so you can use it to power either the tablet itself as a secondary source or whatever I come up with as a power injector...

Oh, and on the otg dongle front... those little buggers would end up being about $14; (and that's based on my volume pricing!), so if there's interest at that price point I'll go ahead and do 'em, but I'm looking for feedback on whether it's worth it or not.

Thanks,
