I will not help much about the license  issue, but It's good to know 
that there is code available to make OpenJUMP and geOxygene work 
together. Maybe time for me to test capabilities of GeoOxygen ;-)

If it's not a plugin but a kind of adapter, it could be nice to make it 
available with small examples (plugin ?) based on GeOxygen capabilities.
That said, I cannot see any reason not to add it to the list of OpenJUMP 
PlugIn. Let's see what Stefan and SS say about that.

Seems like we have plenty of code for triangulation now... Would be very 
interesting to do a complete comparison. I already did some tests with 
JTS and my code but did not succeed with shewshuk code (could not 
compile it for my windows 64 box). I never tested Christopher's code not 
the code of OrbisGIS. I know from Julien that shewhuk's code is faster 
than mine (much faster in the case of constrained triangulation) and 
from my tests that my code is faster than JTS's. But speed is only one 
characteristic  of such a library. Would be interested in any further 
results
