I was also thinking about how we maintain CFP deadlines and I had an
interesting idea

People could create their CFPs as issues in their bug trackers.  This is
not relevant for every project but it is useful for some projects.

In the bug tracker issue, it is possible to specify some attributes:
- deadline
- assignee - a virtual user called "cfp" for public events

Finally, the iCalendar feed from the bug tracker can poll all issues for
the cfp virtual user

I already did some hacking on the latter, there is a script with




There are probably other permutations on this, for example, adding
VALARM to the scripts to give people reminder popups.
