It looks like the OTC Houston show went well. they were in a better location than years past. I could tell from their map and the Halliburton sign behind them (on their facebook page). That should have drawn more new interest and show their staying power to previous interest.
I still believe they have deals which just haven't popped yet. there is too much market awareness of the voraxial for it to just stay idol. Sometimes it takes quite a bit of time for the big shots to make these kinds of investments. I'll be there to see it happen. They are not overly burden by indebtedness like some other companies. Take a look at ESPHE for example. Talk about scary.
