Hmmm. Just cause I'd like to have two from you! (poet and don't know it)
I'm going to be messing on a new xbox with x-ecuter2 soon (if they ever ship the mod chips...). Plan to implement a miniature relay (or 2) on a single switch which will automatically swap my xbox net connection from pier to cross-over if I switch on the mod.
This will prevent going online (unless you mess with other hardware purposely, such as with my wireless bridge, cause it has both connection modes available) with the mod switch turned on. It will also allow head to head direct connect with the mod on.
Knowing me....I'll screw it up, or maybe not. Could pass it on to some less informed, or less furtunate, or back to you if I don't need it.
Cheers!
