Certainly. You are correct it's reverse engineering, and having access 
to the engineering data would result
in a better product.

Of course. :)

Hmmmm.... define poor performance? As compared to what?

Also 25k is very cheap.... many IP cores sell for over a million 
dollars.  Naturally that's relative haha. :)

Ah.... now you have my attention even more... I have been getting into 
SDR recently:

GNURadio http://www.gnu.org/software/gnuradio/doc/exploring-gnuradio.html

Obviously serious assembly required.
