Hope this is of some interst to you..
I finally bought a set of Motorola TA200 Radios and some hand free kits from a paragliding shop..
the kits work with either the Motorola radios, the linus (?) radios and a version is available for the Kenwood radios.
the shop: http://www.sickandwrong.co.uk/
are really good blokes who ride bikes aswell and have a wealth of experience..
The hands free kits are @£38 each and I opted for a push to talk button which is on a long lead and I can velcro to either my helmet or my petrol tank. It cuts out the need to have voice activated which noise can set off.. Ask the lads about them as they are really good and fit inside helmets without any problems..
What speeds can we do:
They work really well upto about 40mph. So around towns - which is their intened use - they do the job. Noise above 40 means you need to speak really clearly.
I am working on positioning the microphones in front of the mouth rather than on the jowl padding to the side of it.. will let you know the results...
What radios are on offer:
The motorola TA200 (@£70)has a good all round use - runs on AA bateries or rechargables - but since I haven't wired a recharger into my XTZ660 I can't charge so batteries do the job - they are after all available from pretty much anywhere.
These seem to be better than the TA288 or the new TA6220(?) - Both offer built in rechareable batteries and encryption but their after-market products are not up to standard - head sets are not universal and the plugs a re non-standard (Trust me - I tries to make an adaptor for the TA288 and you can't get the plugs)
The alternatives are: Kenwood - I think this is the TK3101 - @£160 and others - the quality is probably better but the price refplects it...
Other are Linux - don't know much about these yet....
Short Range Business Radio, or PMR446, is the licence fee free radio communications product which enables users to communicate over a distance of up to one mile. All of the above fit into this cateagory.
Hope some of this help,

I'm interested in learning more about these radios equipment. Could you post some links / company names?
I'll try anything once, twice if it didn't kill me!
