I have been working on new combinations using my MacBook Pro 13, Blackberry Gateway Bluetooth (around $35) and T1. Weather playing back music thru iTunes, MixMiester or any other software it works very good.

Basically, the built-in bluetooth has the ability to transmit and receive at broadband speed and act as a USB cable. The Blackberry Gateway has a 1/8" stereo plug out which can connect to any analog device. If using the T1 then it can go either way. Use it to record whatever the T1 is playing (think Garage Band) and send it back to the laptop via the bluetooth.

When pumped up in my house thru the L1 it sounds real good, no static. If the laptop gets too far away then the signal just dies. I'm good for distances of about 30 feet.

The same works for my Blackberry Storm 1 phone's bluetooth, I get extremely high quality music transmission. I can see this scenario working well at a party with music tracks playing. You can walk around while controlling which tracks to play and at what volume.

I did not realize how high quality the new bluetooth devices are until now. The system can send and receive large files, pictures or whatever you want to send without a cable. The systems can (if setup this way) link up automatically whenever you are in range. This is way more then just a remote control.

if playback music only that's great, otherwise latency is big issue if play live music.

Also, if you want to have longer range, then you need to connect to wi-fi router that will give you more range.
