Yes, hybrid GSM/802.11 phones have been around for a little while.
AFAIK, handoff's manageable if you're the cell provider.
However, to put it bluntly, public WAPs suck for VoIP. Authentication,
captive portals, latency, bandwidth-hogging, firewalling and NAT all
make for a hostile environment.

Well, the OpenMoko is pretty close to that. An N800 with GSM would be a
bit bigger; you'd need rather more battery as well as room for the cell
module* and antenna.
This from a guy who still has a landline,
*Cell modules are COOL. All the circuitry of a cellphone in a ~$30
shielded package the size of a matchbook. I once worked on a project
where we put 4 of 'em on a PCI board. I guess they put 'em in vending
machines so the company can get status via SMS, and parking meters so
people can pay with credit-cards. I often think of uses for them myself.
