Dear Jaap Suter, Your library is more than interesting, actually (at least, for me). I was browsing for its source recently and with no success. It's a very good news to hear that GA library (apparently) will be available in public domain (whether this would be boost or oo-numerics, I don't really care, although I believe that this library should find its place among other boost libraries. After all, quaternions and octonions are already there and one could arguably tell that the use of GA lib would be far more substantial). Sound YES. This library is interesting. Would you be so kind to upload it somewhere? I just cannot wait to see what it contains and how applicable it is for some problems I'm currently working on. Kind regards, Justinas Vygintas D.
