DARPA Grant Cancelled for OpenBSD and U-Penn?

Starrider writes "It seems the DARPA grant for OpenBSD and for University of Pennsylvania has been cancelled (?) immediately and without warning. See the full story in Theo's email and on deadly.org." Theo is left to only speculate why funding was suddenly pulled. One also has to wonder what this means for the University of Pennsylvania, since they were also in for a piece of the pie.
