  My $0.02: use TLS with a pre-shared key.  While this requires a TLS implementation on the client, the administration overhead is exactly the same as for traditional RADIUS shared secrets.

  And TLS isn't much of an overhead any more.  While OpenSSL is huge, there are many other small / embedded SSL libraries.  Any modern RADIUS client should be able to handle TLS without much difficulty.
