What is your licensing concept? Does using GTP.net on my desktop computer and on my laptop means that I have to purchase two licenses?
We license the GTP.NET per developer seat. You are one developer, and you probably have a couple of machines, OK, one license.
Maybe you need it on the build machine as well. Still ok with the one developer license.
Your peer want to use GTP.NET too, he will need a license of his own.
You distribute you application to millions of clients. We are happy for you. No Runtime costs, no hidden costs. We are developers and we know that RT-fees can be the biggest turn off in the world.
