Apologies for my late participation in this discussion, but some important commitments have brought me around Asia's developing nations since the beginning of the year, so everything I have brushed sides with thus far have been anything but audio - mostly "photovoltaic modules", "fabrication", "getting to know more cultures", "funny weather", "no electricity", "crappy internet", "load shedding" and "solar deployments". I don't even know when I'll be back home. Good Lord, are you there?
I concur with all that has been said, most notably with blueprintstudio's opinions. If I were to host anything with regards to Linux and Audio it would primarily be a walkthrough for hobbyists or a demo on Ambisonics (given the proper mics), since I doubt there is enough interest in areas of acoustics, DSP, and sound design/synthesis. The majority of Linux-audio users are the electronic kind, whereby there is some sort of "live coding" going on during a performance - I'm neither good at that nor do I perform live. Someone who is adept at Max/MSP would be a better fit sharing his/her esoteric knowledge coupled with a Macbook. Another audience is that of the academic type, where stuff like the following are all the buzz:

My latest "professional" Linux work (in double quotes because my employer had no idea what I was using; he just needed the result) was back in November/December, and it was post-production. I used Ardour, Xjadeo (a lame but useful workaround for a DAW that has no video window), and Kdenlive (a nice video editor, which crashed in front of the director twice). How I wished I had Ardour Mixbus with Harrison's DSP. Now, you might ask "why the hard way with Linux?" Well, because it tickles me to see how far I can take things
These days information is easily accessible via the WWW, and if we were to host any sort of meetup/workshop, we would have to find a niche where there is significant interest but little documentation - something from which a particular target audience will benefit. So until then, I say we leave it up to SOFT's forums and friendly patrons.
Well, hope to meet up with you guys one way or another, Bar B Q or Beer B Q (just to put a texture on the mental model of your characters). Take care!
