OK, Cees seems to know whereof he speaks, he certainly calls our concerns out clearly, I'm off to read the GNU Library license again.
I'd be curious if anyone has already clarified it's application to the reverse situation, i.e. our VR engine is fundamentally a (great big fat badtempered) plugin library for Squeak. We have no problem giving away any changes we make to squeak or any non-VR code, we just want to protect our copyrights on our core library plugin. Anyone seen how the LGPL has been applied to this, say in creating 3rd party commercial libraries for gnu compilers.
Re the death of IP in general, Cees, I'd tend to agree, software patents show how low we are sinking. On the other hand, one needs to make a living. And in general, if you give it away and ask them to pay if it works, you starve.
