If you violate the license, they'll try and throw you in jail. We add new features quickly and your input about what features you want is valuable. So make a demo available and send an announcement to cola everytime it is upgraded. Heck, this is the demo version. So far, only the one crash I wrote about above has occurred.
Upgrades are available for only six months.
And this is by no means an exhaustive list of missing features. Just what I found real quick. I'd suggest waiting. I now must get NT working first thing Monday morning. I still don't have a cad package to do my work in Linux and then take it to acad to make a final drawing.
