You may want to post to cisco-nsp at puck.nether.net
instead as that reaches a slightly different audience (a lot
of the same people) but has a lot more people that
concentrate on the GSR. (Whereas some people here may
not use GSRs).
I would also recommend some more recent software than 12.0(14)S
as that has a few security issues amongst other things that one
wants to watch out for.
