Designing for Experience

Do you ever have a variety of disparate deadlines and you would like to keep track of them in a very visual way?
Quite often academics have this problem in that there are a number of possible conferences or journal issues that have deadlines not only for submission of your paper, but if accepted you then have a deadline on “camera ready” editions of your work, a deadline for registration, and of course the conference itself.
What if you could see how many days you had left in a countdown kind of style until the deadlines of these various conferences?
This could be a customized webpage or a “widget” associated with igoogle, yahoo, google toolbar, or something native to your OS. Though you could of course enter in your own deadlines, you could however search for conferences and other things by keyword or tags assigned to them as others upload their due dates. One could also create lists of conferences and journals and you could import a list wholesale.
I imagine there are a number of ways this could be used, but this is the one I can think of most readily.
Who wants to make this one? Go ahead and steal it, attribution would be nice, but hey, in this game execution counts for a lot more than the idea.
