Ah, good point. I'm guessing gaps in 3G coverage and/or the unnecessary extra layers of SkypeOut are the risk? In any case, I suppose my idea could be revised to include CDMA/GSM specifically for emergency calls (which would rely on roaming). As far as porting, it would definitely be a nice feature, but I'm not sure would be necessary for a successful market entrance.
