Hi all,
I found this paper an interesting skim, even if only for the numbers and
timings:
http://faculty.cs.byu.edu/~knutson/publications/IrDA_Assisted_BT_Discovery.pdf
It is very much a rehash of the old broadcast vs point-to-point dichotomy.
I don't think IrDA is the answer for most deployments, but it's an
interesting piece of research
as it sheds light on how the discovery mechanisms operate (without
having to read the entire
specification), and how these might be sped up or worked around.
I keep wishing Bluetooth had passive scanning like 802.11 does.
cheers...
