Fair enough. However RADIUS will also work with cleartext passwords in the
RADIUS users file, i.e. Password=my-passwd rather than Password=UNIX,
so although a specific RADIUS server may not have CHAP support it should
be possible to add that support unless there are some problems with field
sizes. 

But the best place to ask this question would be on the RADIUS mailing
list hosted by Livingston and the second best place to ask it would be on
the portmaster-users@livingston.com mailing list. Last I checked both
lists were monitored by the people at Merit who have the most
feature-laden RADIUS server around.
