Anyone seen any ultimate hierarchical information organisers around here

Occasionally, when I get some breathing space, I scout around to see whether anyone’s written the nirvana of information organisers that I’ve been looking for, for a few years now. My current stop-gap solution is Treepad, as I mentioned here.

However, what I really need is:

• Hierarchical structure!
• RTF/HTML text/images/etc
• Seamless cloud sync
• Offline PC / Web / iPhone clients
• All my information, where I can find it, when I need it, in a manageable form.
• Ideally, selective sharing/collaborating of branches
• Today’s wish item: org chart support!

No-one has yet managed it. Treepad does OK, but has no mobile clients or cloud sync. Google Docs, Evernote, and a thousand other note tools, do it all.. except Hierarchies. No people, Hierarchies are not dead. Just because most people can’t organise their information worth a damn and just want to Hadoop-search everything, doesn’t mean I can’t organise myself as much as possible.

Mediawikis are very close, if you create your own hierarchy, but a pain to manage.

So… folks, seen any perfect info tools around these parts?
