It is your work.  You can release it under any license you want.

Si2 is not GPL friendly, not even open-source friendly.  They 
have no control over software that you write, unless you are 
funded by them.  Some of us would appreciate it a lot of you DO 
release it GPL, to make a point.  GPL-3 is even better.
