Is it possible to do this though?  Using the taxonomy I posted earlier, TLS-
SRP would seem to fall into the "modify the crypto portion of the TLS
handshake" bucket (alongside TLS-KRB5 and TLS-PSK), which means that you
couldn't really do it inside EAP.  Admittedly you could do a standard TLS
handshake and then follow it up with SRP inside EAP purely for the
authentication portion, but that seems (a) messy (see draft-iab-auth-mech-*)
and (b) a bit of a waste of SRP's capabilities, since it can do the whole key
exchange step as well.
