Also, there seems to be interest in jidgo; has anyone worked with that
in the past ? and whats to help us get that setup as well ?
Jigdo is a bit of a mess. The code is essentially unmaintained, but it works, if not always optimally.
It's not too complicated, though. Just use the jigdo-file command to make a jigdo template from an iso and set of contained files. Likewise you can use the same command to remake the image from the template+files (or verify it). The man page for jigdo-file is reasonably clear.
There is also a basic gui tool to make downloading and reassembling easier for the end user.
