Thanks, good to know.  That approximately matches what a 1Ghz i686
laptop, PCMCIA 802.11b WEP, linux can do, as a effective (userspace)
802.11b attachment time.

That does not mean that 802.11b userspace attachment time is that good
everywhere, and in some cases it can be as slow as 4seconds, an
interruption delay to which an IP FMIP protocol could presumably do
little or no help at all.

I'm wondering whether it's worth to note down some range of the
"tolerable L2 interruption delay", with actual quantitative limits,
within which a particular FMIP design is known to work and offer a
better user experience, IMHO.  The word "fast" itself in the protocol
name may invite to think about that, IMHO.
