and, so we're clear.  The Nessus test is a *specific* test which looks for
SSL servers which will accept unrequested client-side certs (as opposed
to a more general test which either fingerprints or fuzzes SSL
servers...both of which seem very interesting, btw).  And, if you look at
the code, the section where we weed out MS and Novell SSL servers just
leads to an exit().  i.e. the plugin will never flag or report on an "SSL
type or version".

So, it was incidental that we found certain systems (Microsoft and
Netware, to name two) which responded (how shall I say)...anomalously.
It was never the intent of the plugin to do anything more than test for
one specific bug.
