How about getting in touch with the guy that is running jigle to see if he could customize his software to only include full sources?
GCW being such a well known and respected site, I'd assume he might do it.
His email is on the page linked to below (don't wanna cause him spam...).
If you are satisfied with only partial sources you can include a jigle-feature as it is today:
