do you have to redo it?

GladeVCP would go some way towards that, but you really need something similar to Khoros'es old Cantata <http://www.cs.colostate.edu/cameron/khoros.html>, VisTrains <http://www.vistrails.org>, or similar. (please note that Khoros is defunct, was sold off, and the opensource license was basically pulled -- which still pisses me off 10 years after the fact)... > Wouldn't be interesting to have HAL as a independent set of packages > upon > which LinuxCNC depends?. > > I think GladeVCP could ideally be a package independent of linuxCNC > depending upon HAL. > > I think that this phylosophy already exist, even for the > documentation -atl > least to some extent-.

As a ntoe, I have not chased down all the licensing issues, but this would give you a thought.
