Depending on when and where it is, I could lend my tools and my experience. However, IMHO, with barrel-less kits, it's quite a bit of a PITA for a build party, as not only do you have to take time to do the actual build process with riveting, barrel install, etc., but you have additional time to factor in installing the barrel components, headspacing, and drilling and installing the new barrel pin. To me, it just isn't worth the extra work. Now, if you had a kit with a US barrel already installed and headspaced, it wouldn't be nearly as bad.
If you're serious about doing a successful build party, I always recommend that everyone have as much of the demil done as possible prior to coming, and if at all possible, to use a Nodak receiver for their builds. It just makes the process much easier and less time consuming. Granted, building from a flat is one of the biggest appeals of doing an AK build, but trust me, when you've got 10-15 people all wanting to build AK's from a flat, factoring in the actual receiver construction, heat treating, demil of the kit, and the eventual building of the rifle and hand-fitting the kit to the receiver, it turns into a multi-day process, rather than just a day long get-together/build party.
