I've helped a friend to get started with Debian packaging and he has now adopted python-ipcalc. Since I've no prior experience with packaging of Python modules and there were five years of upstream development in between, I've uploaded to experimental to give it some exposure.

So if you still use the python-ipcalc package, which is part of all current Debian releases and the upcoming jessie release, please check out the package from experimental. I think the only reverse dependency within Debian is sshfp, that one of course also requires some testing.
