I'm glad that nobody sees a massive flaw in the scheme.

The MiFi also spans a local WLAN (a poor man's PAN), so by
switching it off (Huawei ones boot in ~5 s, so it's not
a major PITA) you're also depriving yourself of an (untrusted,
of course) LAN.

Many mobile networks operate with carrier grade NAT, so with
MiFi your WLAN devices are already behind two layers of NAT
or more. 

So far stock solution for VoIP has been SIP, but SIP is a terrible
protocol to tunnel through NAT. So far the only contender I'm
aware of is Jingle, anything else I'm missing?
