That's already possible via the git-commits-head@...r.kernel.org email 
list. Anyone can subscribe to it and can procmail process it. It is also 
more secure (and less intrusive to the tree owner) than any post-push 
hook script running under the pusher's UID. Polling via cron is really 
not required i think.
