Thanks everyone for your support.
Alex is one of the devs involved in this project. I've to admit that I don't know him personally and I also can't grab him anytime I want but I trust him and I admire his work. He says he has started to write a working implementation of his paper so I'll ask him for a detailed roadmap.
Currently the former dev and I are trying to upgrade metacoin basis code to bitcoin 9.2.1. I run out of time recently because of my main job taking over, but I'll get my holidays in few days so expect to see a big jump in the next weeks. I also try to create a healthy environment for the coin to succeed (website, forums, documentation, developer website, IRC...). This take time especially as it require a lot of knowledge in web development and i'm not particularly acquainted with that.
If some are interested in joining and help us (Marketing, PR, coding...), feel free to leave me message.
Now that this coin has finally caught my eye, I will keep tabs on development.
If you are one of the small handful watching this project, might be good to hit up Poloniex. Bittrex would be great, but they tend to go where the money is. Poloniex has a better track record of taking on the more obscure coins. A great way to give a coin exposure is to simply get it on an exchange.
