Someone at the CRAPS BOF was adamant - and I agree - that
seamless mobility should support handover between access 
networks (full stop).
 
By definition, some of these access networks may be wired. Some
of these access networks may involve wireless links where the
sensing and calculation of RSSI is either meaningless, or uneconomical.
The origin of the "handoff trigger" as someone called it, is the 
purview of the access network designer, not SeaMoby.

These seem to be related to a particular network technology, right?

That is ... given a network (radio/spectrum) design ... then "network
handoff triggers" are determined by the network designers ... and these
triggers can use such information to help determine when the
"triggering events" should be requested, right?
 
Is this not for wireless networks?
 
If so, then EVERY wireless network has a RF signal.  Not just Bluetooth.
And every radio I have ever put my hands in has had a RSSI.
This includes Shortwave, VHF, UHF, Microwave, Bluetooth and yes even cell
phones.
This is how a radio measures the signal strength.  Some radios called it the
Recieve Signal 
Strength Indicator, while others call it the Radio Signal Strength
Indicator.
This is fundemental.   Fundemental wireless terminology.
Look on your cell phone display, you will see it.
 
If you want to come up with a wireless protocol you must be willing and able
to learn and use some basic wireless terminology.
 
If you are working on a wired protocol then you should say so.
