I was actually expecting that, to get this to work well, you'd need 
to purchase the 3GPP/802.11 roaming service from a single provider...

I know that this isn't how we typically do things in the IETF. 
However, I am not sure that we are doing this in the IETF.  The only 
place I know that this particular problem is being considered is in 
the IEEE (802.21, IIRC).   It also seems likely to me that some of 
the cell phone standards bodies are looking at this (3GPP or 3GPP2, 
for instance), but I haven't heard of anything specific going on 
there, have you?

I think that mobile IP could be used for something like this, but not 
without cooperation from the cell phone providers, right?
