I wholeheartedly agree here, maybe not UBF, but certainly
an application specific protocol as opposed to full distribution.

The authentication of the connecting parties must still be

using a shared secret. The algorithm is semi ms-chap v2 but
with md5 instead of md4 and all the ms versioning cruft removed.
