dropbox-like file drop app on web server?

[Alan Young]

Due to some yak shaving (I got sidetracked looking at stuff for
gitolite) I found this article that seems to describe something like
what you're describing:

"I primarily use wildrepos in two scenarios: managing documentation
and development for my research team, and homework submissions for my
classes. Both of these scenarios use all the features of wildrepos
including non-admin repository creation, user-level permission
distribution, and group management."
