Replying to myself...
I dismissed commercial solutions (proper radio modems) because they all
looked too expensive. But I've found a beauty:
http://www.rfsolutions.co.uk/products/radio_gsm_modems/Addlink.htm
38x21mm, RS232 @ 38.4Kb full duplex, 15Kbit rf, integral antenna, just under
£30 (~$50) each for single units. In "Null-modem emulation mode" it sounds
ideal.
Not ultra-cheap, but there should be very little hassle making it work and
it's very compact.
I expect I'll be picking a couple up in the next week or so unless someone
more knowlegable than me tells me it won't work. I'll report back.
It may also be of interest to wireless freaks that I'm looking at a wireless
camera solution too:

eno=27670&modulecode=
(just a *bit* smaller than the x10 cam, eh?)
plus 2.4GHz receiver,
plus (my existing) WinTV card
