I jumped wrongfully to the conclusion that JsStar was closed and couldn't be used commercially. I must admit to being a bit rusty on anything legally attached to software which isn't GPL or LGPL :) However, I received the following confirmation Seung Chan Lim of Maya Desing this morning;
"The distribution is not GPL, but it is still free for use (commercially or non-commercially). The GPL or other open source option is being discussed, but we just haven't come to a conclusion yet."
So, as soon as they have the 0.95 version ready, it will be freely available and usable, maybe even as open-source. So ther. Sorry if I was abit unclear before :)
