William, this could be really great, for many reasons - perhaps even
funding. I am cc:ing this to sage-edu, as some people there probably
will be interested. I am certainly interested in trying it out, if I
can figure out how :)
How did you envision the applets integrated into the notebook - on an
on-demand basis for @interact-like things for specific purposes (say,
drawing hyperbolic triangles), as a menu option "insert a Geogebra
applet from list X here", or something more integrated than that into
the Sagenb spkg?
