Could you upload the patch somewhere? And did you commit XoWiki to the CVS in the 5.2 branch (or head for that matter). This is definitely something with which I can finally put ETP to rest for our site, at least from the looks at it.
As for Xinha, is it possible to reduce the number of features using a parameter in acs-templating and thereby make it quicker to download?
Furthermore, has anyone thought about a method to support multiple editors within OpenACS?
