Aquaduct, the superior Xbox tunneling app for Mac OS X, has been updated to beta 3 today. The changes since beta 2 include:

• Xbox detection column graphics added.
• Working pings.
• Client/server code overhauled.
• DING button added.
• GUI cleaned up.
• Help Files!
• Numerous small stability enhancements and other minor changes.

Looks to be a good step forward for the software. Pick up beta 3 and make sure you have GameRanger so you can find other people to play with.
