lol dan you know that bitshares is way more advanced but etherdelta is great for buying tokens easily with metamask before anyone on the exchanges has access.. Do you think that the openledger dex or any other could integrate metamask into their exchange? Is it technically possible?

I think it should be possible. The application only has to communicate with the web3js object. I assume EOS will make something similar to the web3js approach from ethereum?
