Dave I don't follow 100%, so let me ask a few questions:
"Give every site-node a cr_folder in this tree." - You mean every site node in the whole openacs site, even ones not nominally under cms control? How would this be kept up to date?
"This way you could add a page under forums for example, and it could be managed by the CMS." - it seems to me that that would require modifying (and slowing) the openacs request processor, since it would have to check for valid cms pages everywhere - or at least as a default failover (actually not such a bad idea... but still a pretty radical change).
regarding Robert's idea about portals, rather than a UI, i think we just allow designers to do something like <include name="top-news" count-value="10">. This would include tcl/adp pairs from initially a folder in cms, but ultimately should be db based as well.
