Hi Antonio, I would very much like to do that (re: tutorial) though later in the summer as I'm somewhat swamped with a number of different things these days. That said, I would be glad to contribute in the development of the existing templating system or even integrating the two systems if the community finds that to be constructive. Overall, I'm all for contributing more in open-source projects, and OpenACS in particular, including bringing the work I've been doing over the years to converge with the existing codebase. Not sure what the best way is just yet. Just letting everyone know that I'm willing and, hopefully, perceived to be able to get the job done.
