Since (I think) Arduino 0019, and definitely by Arduino 0021 there is a UDP API in the core Ethernet library.  If you look at the Ethernet examples there are two that use UDP.

Unfortunately, the API is due to change a little in the next release (or maybe the one after).  See https://github.com/arduino/Arduino/pull/19 for details of the proposed changes.
