Since Houdini itself is a clone of a program (Ippolit) that was clearly based on disassembled Rybka code even though greatly modified, I think it's pretty funny that you object to others decompiling Houdini. I would not encourage others to decompile an original program. In my view Houdini forfeits any rights to object to others disassembling it due to its own origin. I don't think we have used any original Houdini ideas in Komodo, but that's because there are so few of them, not because we consider it wrong to do so.

I don't agree. We assume Houdini is a combination of Ippolit and Robert's improvements. The Ippolit portions are freely available to anybody. Robert's improvements if he doesn't want to share them should get the same protection from RE as they would if they were housed in a program he wrote from scratch.

Larry is implicitly stating here that he has the copyright to parts of the Ippolit code, by extension this code may be found in all its derivatives. He has stated before on this forum that there are tables in Ippolit that are directly traceable to Rybka, of which parts he has the sourcecode.

Copyright is shared with Vasik Rajlich, but Rajlich has indicated in the past he did not think it worth it to legally do something about this. Short of the legal road the only body we have have that could give some official verdict on this would be the ICGA, Ippolit has never as far as I know requested to participate in the World Championship that is organized by ICGA, but if the 'consensus' would be understood as such that Ippolit is now public domain, in its entirety, inevitably, if it is not clear which parts could be copyrighted by Larry Kaufman and Vasik Rajlich, these parts could turn up in participants code, without any intent of wrongdoing. So that seems to me enough ground to investigate this further, and may also be seen as necessary for any possible review of the Rybka case itself should this ever be requested by Rybka's author(s) or representatives thereof.

This just as an outsider's opinion of course.

Regards, Eelco
