Is it fair to say InstantDEX, BTCD, and SuperNET are his biggest projects to date?
Are any of his software projects out of beta?
MGW was completed more or less a while ago. Not sure what the official status is in terms of 'beta' or not, but it's been working for a long time. InstantDEX is in testing too.
Anything that's in beta though is pretty good though as a beta release generally refers to something that is feature complete.
There are a lot of projects that he's involved with. Last year most of the criticism was that he was taking on too many projects and that there was no way he would be able get anything done on them all. But SuperNET kind of took all of the individual projects and combined them in to one meta project. He's pretty much completed his end of the bargain for the large majority of the projects, there's still a lot of testing that should be done by others and such though. He just does the coding. All the other stuff like marketing and such is up to others.
