Hello,
While not a developer, I am an active Morphix, um, "helper." I work on
a project called Intellibuild, which helps one create LiveCDs very
quickly and easily. The next versions of Morphix will be built entirely
using Intellibuild (http://ibuild.livecd.net).
One othe biggest things needed to include a program is a .deb source in
our sources.list file. Since you already have the .deb, but it hasn't
been included in debian.org, you could simply make a packages.tz source
one your site and let us know on the Morphix Mailing list the source
address to use, and it will most like be added to the next Morphix
LiveCDs (or at least on many of the ibuild variations).
Thanks,
Kermit
