Diego,
I'm not sure exactly what Lectrosonics has planned for development for OSX, but I hope they add support.
There are software packages that allow you to run windows software in OSX without doing a full installation. I've used them in the past and they can be a life saver - when they work. Setup can be a bit tricky, and not all software works, but If you are tech savvy, you should be able to give it a try. Setting up LecNet like this is on my Todo list, but I'm not sure when I will be able to get to it.
CrossOver. Commercial, with some direct support
Wineskin. Open source with community support
