I'm not sure if economics are the worst part of what is being shipped,
to me the worst part is security, I'd never trust myself such a
non-open-source TCP stack for something critical even if it was going to
be much cheaper and performant. Even my PDA is using the linux tcp
stack, and my cell phone only speaks UDP with the wap server anyways.
TCP segment offload OTOH doesn't involve much "intelligence" in the NIC
and it's very reasonable to trust it especially because all the incoming
packets (the real potential offenders) are still processed by the linux
tcp stack.
