Any OOPSLA attendees doing XP designfest on 3/4 day Wed?

Hi All:

        Looking for fellow Rubyists to sign up for OOPSLA XP designfest
3/4. With the XP designfest, they're not just looking to do a design,
but the implementation as well. I'm guess most will gravitate towards
Java or C#, but I want to do it in Ruby.

     Any takers?
