I just checked this out, and it looks like he's gone totally Linux because Windows and the Anti-Virus industry has been giving him too many headaches. From the main page:
I'M SADDEN, BUT PLEASED AT THE SAME TIME , TO ANNOUNCE THAT WE'RE NO LONGER OFFERING WINDOWS SOFTWARE - WE'VE MOVED ON TO LINUX SOFTWARE DEVELOPMENT.http://www.code-it.com
To our past loyal customers - we've got a lot of explaining to do - and here it is...
I wish him well in the endeavor, and according to his software page: http://www.code-it.com/software.htm
he's looking to fill niches that current Open Source projects aren't exactly filling; in other words, it sounds like he's doing it for users, not for himself. Which is HIGHLY unusual in the Linux community to start that way; most projects start as a personal "itch to scratch" before they go on to be big user-driven projects. Also mentions he's using the GAMBAS IDE, which (for better or worse) is a fairly decent replacement for Visual Basic.
Looks like everything is open-source for now, I'm curious to see how he does with paid-for software.
