My definition of RF includes near infra-red. Call it Electromagnetic
Radiation if you prefer. Maxwell's equations still apply. 
 
Whether it is:
 
- IR
- 802.11
 
We still can measure a signal strength.
 
But, you make a good point about switching between being plugged and
unplugged.
 
This suggests to me that L2 should handle roaming (seamless mobility) in a
homogenous network, because some networks like a LAN do not roam.

Wait a minute - are we assuming it's RF? I'm thinking I have my laptop with
an 802.11 card and an ethernet card - when I can plug into the local LAN, I
do, and that becomes my primary datapath. When I unplug, the 802.11 card
becomes my primary datapath. Maybe I have an IR transport of some kind. I
don't know, but the point is that mobility has to handle any kind of
transport, and should seamless mobility assume RF?
