So, technically speaking, a bar mod would be possible right now, there just wouldn't be anything to put on it? It would seem that someone would want to lay the ground work down and as the devs release more of the API that things could be added to it.
My main question though is about the "profile handler" addon...is something like this even possible. I know form WoW that profiles are a mess...some addons have them and some don't, but there is no addon that has a standard meathod for saving profile information so that an addon could control the profiles. I am sure that we have all had to experience completey resetting up a UI from scratch because of a reinstallation. It would be great if you could just drop a file into a folder and then install your addons and just select your profile and all of your addons would reset themselves up.
Just a thought.
