Thank you for the hint ! :-)
I found a java implementation that was released under LGPL:
the original C code is also freely available in an RFC, http://www.ilbcfreeware.org/ with a somewhat permissive license: http://www.ilbcfreeware.org/documentation/gips_iLBClicense.pdf
so maybe I can find some time to port the java version into C# this year :-P.
and I am looking at CELT too, but they need to stablize the bitstream format first.
