how many clients use TCP Radius

[Florin Andrei]

What clients actually use Radius over TCP? I can't find anything out 
there that's widely deployed and can query a Radius server over TCP. 
E.g. the Cisco documentation for routers, etc. seems to indicate that 
they only do UDP.

The reason why I'm asking - I'm looking into setting up authentication 
for a variety of clients, with Radius used as a transport protocol, and 
I'm wondering if it's worth the trouble to even think about enabling 
TCP, or promising I could offer TCP.

Thanks,
