Are there any solutions to this issue yet? We're reworking our entire framework that (prior to my arrival) was a mess of Prototype, ColdFusion CFAjax stuff, Spry, you name it. We're slowly replacing other code with jQuery calls, but it's not going to be an overnight process...and we still have to keep the existing site running. The noConflict() doesn't completely solve all our issues, but sure made a big difference.
