Samir, thank you very much for the update. Either me or Roberto will add the posted open items in our todo list tonight. A generalized xml import/export service would be great. I suggest we wait until I post a RFC about adding support for tDOM in the OpenACS kernel at the end of this week. tDOM is way faster than ns_xml and more feature complete.
You and Robert could discuss in what ways your work on the FAQ package intersects and let me/us know who is going to be the package maintainer. You can be both, of course. Let us know if we can help in any way.
