Is source code for PokerStove available?
No. If you are looking for source code, I would recommend going to the pokersource project at sourceforge.net. It is excellent code and runs the back end of the Twodimes.net poker page. The code is available under the GNU General Public Licensee (GPL). I have made a version of my old Java Poker Library available. It is fairly stale code, but you are free to use it with no restrictions.
