I was not under the impression that this system was intended only for the
use of Debian Developers.

I do. I think it's a fairly significant one.

Hm, that's interesting, but I suspect that few enough of our users will be
able to use such a thing that we shouldn't let that influence any other
design choices. Most shares are not going to be able to be mounted
through firewalls, for example, so that form of the debug symbols won't be
available to quite a few users.
Or maybe by "share" you meant something that was more like a file download
service over HTTP than, say, NFS?

I thought you were planning on automating *this*, which I think is more
useful than providing a share. It seems like it would be fairly
straightforward in conjunction with the Contents database and the ldd
output on the binary that crashed.
