Carl,
Yes, I would be interested and love to get involved with the happening. Unfortunately the date is impossible for me so I can't make it there this time. My heart is breaking but still can't make it :(
For anyone who's wondering whether or not they should attend the meeting the answer is a definitive YES. There won't be many other circumstances where you can meet (and work with) so many smart, warm and positive people at the same time. Having a thriving online community is great, but you'll without question get an extra boost in working with OpenACS from a meeting like this.
I'd still like to see OpenACS people even this spring so if you've got some spare time on March 25th to 26th, have a look at this thread.
