The post referenced below was the most encouraging thing that I found in that it confirms some of the conclusion that I came to. Also thanks for the references to the status of next release. Helpful in knowing what's on the horizon.
http://forum.joomla.org/index.php/topic,53984.0.htmlThat pretty much says it. The hacks are not for the faint of heart. And inherent architecture/design issues are the reason why many are having trouble finding the 'definitive' answer. It's known, it's being addressed and until then, there might not be an easy answer...
Make a decision on how much time you are willing to spend on work-arounds, and which features/modules/components you are willing to live without. If a certain module isn't working as expected or at all, perhaps there is a substitute.
Meanwhile thanks to Stingrey and everyone else on developer teams, forums, etc. comitted to making Joomla a great choice for CMS.
By the way, is there anything that could give us a heads up how the new security feature(s) are designed and how it would work?
Thanks again.
