That would require some serious voodoo as these are nearly always 
managed by different entities. So essentially this would keep the 
problem the same but require wifi base stations and gsm/umts 
infrastructure to solve this and hide the complexity from the hosts. 
This isn't traditionally the way the IETF does things.
