This is pretty meaningless actually. It's 'just another' exchange in the US - there are already plenty, you can trade any stock you want on any exchange you want. There may be other (laxist) rules for primary listing on that exchange, but other than that, it doesn't add any value - there will probably be close to 0 volume traded on it. And the servers will probably run in the same data center that current NYSE.
If the servers are actually located in Texas, and there is some volume traded, then it could get interesting as in the US, there are rules about 'best execution' that restricts how and where brokers can trade.
