You are right, Bitshares allows anyone to create an asset that could represents anything and use the DEX for an open market exchange of their token. some companies are already doing just that already; such as BLOCKPAY, OPENLEDGER, EVETAB as well as some Steem locals such as STEEMFACTORY, WANGCHANGE, VIRGROW and STEEPSHOT there are many many more but this just gives you an idea.
We also have a few Android apps such as Smartcoins Wallet, Blockpay, BTSBOTS
It is a great project to watch and there are many more developments in the works making for exciting times ahead.
Thanks for the great comment :)
