To complete the picture somewhat, PIX runs its own microkernel-based OS, written by the company which originally produced the product (Network Translation, Inc.) Cisco acquired NTI in Oct. 1995. I believe that NTI originally called the OS "Phoenix." My recollection is fuzzy, but I think the NTI intent was to do a trusted system over a microkernel. I've seen the OS referred to as "Finesse" as well since the Cisco acquisition. AFAICT, PIX is the only thing running that particular OS. The other examples cited are used extensively in the embedded device space (from microcontrollers to point of sale systems.) Of the three, I think VxWorks is the most *nix-like, but that's just an impression from scanning the Web site a while back.
