So at least part of the hardware _is_ Hydra. Take away the custom hardware and it is no longer Hydra. Chrilly has spent years working on the system, and this is after he already had a lot of experience with a pure software solution. (See here for one easy to read article http://www.xilinx.com/publications/xcellonline/xcell_53/xc_hydra53.htm) It makes no sense to run other programs on the Hydra hardware, unless you're just talking about the x86 portion of Hydra. If you think that it's fair to talk about other programs using Hydra chess processors, then why not say that Movei could be run using Shredder libraries and get a high ELO? Why is custom hardware fair game, but software is not? I have a feeling that Chrilly has spent a lot of time balancing the system, and even if you did let others try to use his chess processors, that they would have a difficult time getting good performance out of it.
