If the private address space mentioned in RFC is not enough they should
go for IPv6. Because GPRS, UMTS and other stuff is brand new I see no
problem to implement IPv6 in gateways (and terminals). Another issue
is that roarming. Why roarming have to use unique IP numbers to work?
You could use application level roarming solution as well and nobody
cares if the source addr have gone trough a NAT box or not.
This thing is going to get messy when we get first GPRS phones out.

It's not about the software, it's about usability. I haven't found yet a Word application
for my PDA, but I do have a browser :)
