I just finished reading a great article in 
_The Computer Applications Journal_, July 1994,
about "IrDA".

The IrDA specification is from 0 to 1 meter (minimum),
at baud rates up to 115.2Kbps.
It's all digital, but it's pretty trivial to convert
manaural speech to 64Kbps and back
(phone companies do it all the time).

The IrDA folk (510.943.6546, fax 510.934.5241) were real friendly about 
sending me info, but they'd really like me to become a authorized
developer for only $500. um, maybe in the next millenium.

California Wireless (408.249.7300, fax 408.249.7301)
were prominantly featured in the article -- an actual
*photo* of their product's assembled PC board (rather than your
typical block diagrams of vaporware, or even photos
of a case that could be empty for all I know).
All I know about them (so far) is what i've read in that article.
