Hi Rafael,
I think ETP 2 is not mature enough in fact I don't think its already finished. We have an internal code called modetp - its whack hack attack of ETP 1. I think I posted it somewhere for download. But we have an updated one I am glad to post it up. The core is still whacked up but it works.
Since modetp support multiple templates the student can start doing the adp and very simple tcl. Its a good starter. Some of our developers just do the index.adp and index.tcl templates stuff to build a complete site.
Would you like a copy of modetp?
