Log Message:	- Implemented AppleTalk-over-UDP tunnelling, activated by setting "udptunnel" to "true". This uses the BSD socket API, so it's fairly portable (currently only imeplemented under Unix, though). This works by sending raw Ethernet packets as UDP packets to a fixed port number ("udpport", default is 6066), using IP broadcasts to simulate Ethernet broad- and multicasts. Currently only tested with AppleTalk.
