I honestly, don't quite follow where the conspiracy theory thing fits in. I asked myself, and he doesn't follow it either ;-)
I don't know why it would necessarily be a "bad" thing if it is used in the PIX, or a router, or a switch, etc. In offline conversation, someone mentioned PR reasons, and while I never like them, I suppose there could be some validity there. The original point of this tangent, IIRC, was in regards to statements of "firewalls are only as strong as the OS". Whether that OS is W2K, .NET, NT, Solaris, Linux, IOS, PIX OS, CatOS, Xenix, QNX, BSD, LynxOS, or any other OS someone feels like adding to the list, the statement is still valid. My only point in this thread, lost long ago, was simply that. Not whether Cisco ran other RTOSes or not, but simply that the statement is pretty much a universal truth, not some ISA specific issue (I really do think that numerous people on this list can not separate W2K from anything, much less ISA and IIS). I think part of the problem is that people (me included) said they thought that there were at least some other RTOSes that Cisco used, but weren't sure in what products they might appear. Unfortunately, Brian came out decrying it as a "legend", when there are a number of press releases, as well as a few articles that seem to indicate that there is a good chance that at the least the router, content switches and MGX WAN switches use some other RTOS for at least something. It would have been better, IMHO, to have said something more like "yes, some Cisco products may well use them, but the PIX and anything IOS based do not".
