P.S. I've sponsored the current ESX transformer and that costed both time and money so I am not updating neither the gist nor the transformer until we reach somehow an agreement that can move this proposal forward. If that won't happen, I might still try to adjust the transformer and update the gist to represent my latest attempt just to prove everything can work and does work as expected already, but FYI please don't take the current gist or transformer for granted, as it's clear things are moving pretty fast (although my latest attempt is close to what we have already as ESX transformer).
I am updating all posts specifying this after posting this comment so that new-comers will also be informed about the current state of both gist proposal and transformer. Thanks for your patience and understanding.
