matlab2tikz and dual BSD/GPL licensing

[Ben Abbott]

All,

The project matlab2tikz is now able to handle surface plots.

I've contacted the author about using a GPL based or compatible office. 
Currently he (Nico) has adopted the BSD license promoted by MathWorks, but 
likes the idea of licensing under GPL. 

Is it possible to license both under BSD and GPL? ... and how might that be 
done?

Can a function licensed under the ML BSD license be included in Octave's core 
or on Octave-Forge?

Ben

p.s. some might recall that matlab2tikz relies upon ML's inputParser function. 
I've developed an implementation using the old ML OOP.  Minor modifications of 
matlab2tikz will be needed to run under Octave.
