We're using extbase for domain modelling and have realized the tree by 
ourself using extjs in an own be module.
Going in this direction will lead to some other problems that has to be 
solved - as it is not that easy to use TCEForms out of extjs. We write 
the forms ourself and don't care about TCEForms.

At the weekend i've stumbled over a project related to TYPO3 4.5

http://forge.typo3.org/projects/show/typo3v4-extjstrees

Have noticed nice class diagramms there. Code seems to be available via 
git - but i don't know about the current status.
