We have htmlarea working with BCMS on several sites. I'll send you an email with a password to take a look on one of our client sites. We'll try to get a demo area set up on Aristoi in the next couple days that we can give wider access to.
It's at http://www.aristoi.biz/bcms
Admin access on that node for all registered users. Or use
user:bcms-test@aristoi.biz / pass:test-bcms
Serves as testbed so it might be flaky from time to time.
