This is more of a marketing (ugh) question as opposed to technical...

There is so much talk about wireless sensors in the industry
publications, but I don't know anyone who knows anyone who uses these.

There are quite a few companies (start-ups, most likely) that are
offering different transceiver options that do routing and mesh
networking and all sorts of fancy stuff or just simple point-to-point.
 The DOD is looking for "smart dust" to be deployed in war zones. 
Berkeley has their (open-source, I believe) "motes" with custom
software that is being marketed and developed in parallel by another
company (Crossbow Technologies).

Does anyone on the list have any knowledge or experience of these
things leaving the theoretical domain to be used in somewhat large
scale?

I'm thinking along the lines of building automation where the danger
of having wireless sensors unavailable due to interference isn't a
real big deal and people might be interested in the technology to
reduce installation costs.  The use of wireless sensors in laboratory
settings seems more of a gimmick than something with very much
practical use in the near future; although, I expect that will change
in time.

For example, Kele has some stuff on their website:

I would also suppose that oil well operations might be leaning towards
wireless due to scale of the plants and the harsh conditions that
sensor cables might otherwise have to contend with.

Any thoughts on these matters or parallel matters?

Thanks
Bradley
