I just had a very interesting and successful use of the networking on my 7600. I was that a client's site trying to debug a system. I managed to install the Bluetooth software on the system and without any prior Bluetooth experience managed to get the system on the Internet through my 7600 with an EV DO connection, it only took about 10 minutes of set up!keep in mind , I've never used Bluetooth before in my life.
My programmer on the other side of the country then successfully used VNC to run my clients computer and do some additional debugging. The lag was very minimal and overall quite successful.

so far so good,as far as data connections.
