I don't see why we can't walk and chew gum at the same time. We're having a discussion of features and pros and cons. There's no need to wait to have that discussion, especially since the list of features we want might change IB's willingness to develop it.
Because maybe there's other things more important and better suited for Flyertalk? You know, like a properly functioning mobile app (and if you truly want beta testers*, I'd bet the farm that you'd have a list of f/t'ers a mile long volunteering [myself included])
*as opposed to the mishegas created of having a trial where only those given permission to test it but only in their own forums couldn't follow simple instructions
