If they started at retiring age they'd be dead before it was even
half finished if chipsets are included.

Nowt really wrong with PAP inside EAP/TTLS. At least, no worse
than MSCHAPv2. With PAP the password is encrypted inside TTLS, and
you can store it securely on the server. With MSCHAPv2 it's the
same level of encryption over the wire (as the MSCHAPv2 is easy to
break), *and* you have to store easy to break NTLM hashes on the

i.e. EAP-TTLS/PAP is arguably more secure.
