I'm astonished at the dearth of grant applications this time around. Grant votes are coming soon and I checked the queue and we need more proposals in. See How to write a proposal for more info. That not only includes the information we are looking for in a grant application but also sample ideas of things the Perl Foundation would be interested in paying money for.
For more "behind the scenes" info which will give you an idea of what we'd vote for, see this blog entry about it.
