Just received the following missive in my inbox:

FYI: The status of the mussh source package
in Debian's testing distribution has changed.

Previous version: (not in testing)
Current version: 0.7-1

I'm trying to get mussh into the main Debian archive. Should happen this month, unless I hit any snags. The potential package for inclusion is here:

You could look at this as the very first step in Debian World Domination. =)
