Curious, how does that deal with a scenario in which there was an 
intermodal port wireless -> fixed-line? Or does this just not tend to 
happen to any non-negligible degree?

If so, I wonder if that may change with the advent of MVNOs whose back 
side is a VoIP-oriented CLEC + the regulatory movement toward non-LEC 
ITSPs owning their own number resources Is it reasonable to expect that 
all mobile numbers operated by some sort of "enhanced" wireless provider 
(e.g. a boutique MVNO) will be homed to the big networks' number blocks 
which return a wireless affiliation?
