I would consider you to be very lucky to have not run into a firewall that auto-blocks all UDP. Both my high school and my first employer blocked UDP altogether. (The former went as far as only white-listing outbound TCP connections on ports 21, 80, and 443, with ports on the latter two being transparently redirected through a very restrictive filter.)
