In fact we are interested to collaborate on this. 
But the priority is put on the interface between operator and SNL.
We have a first version based on CGI communication and WEB pages and will improve this.
The graphical tool to generate SNL code is second (if necessary).
There are standards to create SNL code in the PLC world. I would propose to follow this 
direction to be able to buy a drawing tool and concentrate on the SNL implementation.

The standard is called IEC 1131-3 and the organisation supporting it is PLCopen.

Several companies already provide tools to generate pseudo code which could be converted 
into SNL code.
