This uses UDP with a non-standard port. Personally, I would be wary of poking a hole in my firewall to make this work.

Why, exactly? To your point, it uses UDP on a non-standard port; forwarding the traffic won't expose any of your existing behind-the-firewall services.

Anyhow, one of the draws of UDP for this stuff is that it's possible to do clever hole punching so that you don't have to open the port. http://en.wikipedia.org/wiki/UDP_hole_punching
