Interop for gss-gex-sha1-*

[Joseph Galbraith <galb-list%vandyke.com@localhost>]

I've an implementation of gss-gex-sha1-* that
we are looking at shipping soon.

Does anyone else implement this?  I'm looking
to do a interop test before we put our implementation
in the wild.

I recall someone out there mentioning having an
implementation, but I can't find the email anymore.

Thanks,

Joseph
