EVEN,
The only evidence I have as to this crew's future activities is circumstantial at best and still highly speculative considering the facility with which these people operate their "businesses." This, of course, presumes that there actually are numerous people involved which I, personally, seriously doubt.
With that said, the possibility of them moving into mineral discovery and development follows the pattern they've developed with the Trezac/Millagro/Telatinos shell. I could also see them "going public" with any or all of their "wholly owned subsidiaries" with more 504 exemptions.
It seems to me, though, that the VoIP product is already passe. There are just too many major players now for this to be a viable market. If they were to stay with the technology track I would expect something dealing with the area of quantum computers.
Good luck to you in your endeavors. I keep watching this for the entertainment value alone and continue to be grateful that I missed out on this "opportunity."
