I decided to stop being a Bluetooth newbie and start programming the darn thing myself. :-) So I downloaded the NXT developers kit and started to make myself familiar with the API and protocols. My programming language of choice is Python, so I decided not to waste any more time with the existing (and rather unreadable) Perl code, and instead start from scratch. Python supports Bluetooth sockets natively on FreeBSD, without having to install any additional modules. In fact I found out that it's ridiculuously simple to open and access a Bluetooth RFCOMM socket from Python and talk to devices. I'll probably release my code under BSD license and submit it to the Ports collection as soon as it's ready. Thanks again for helping me to start off with this!
