Please wait until you see a complete implementation that actually works. I'= m=20 sitting here quietly, following (and now breaking) the "If you can't say=20 anything positive, don't say anything at all" line because I think that the= =20 more into the implementation details people get, the uglier this is going t= o=20 show itself to be. I'm perfectly willing to be proven wrong, but haven't se= en=20 anything so far that's even begun to convince me otherwise.
