[Gvsig_english] gvSIG and other open source projects - what is your opinion

[Wolfgang Qual]

Dear list,
I have some experience with GRASS/QGIS as an alternative GIS programme of the 
open source sector. What is your opinion: are there links between the 
different solutions? Maybe collaboration possible (for example: open GRASS 
vector layers in gvSIG?)? Contact between the developers?

I am curious about your thoughts...

Best,
Wolfgang
