  IANAL, but it sounds like there are more serious issues than the money.

  If that NDA says some fairly typical things, and if the FreeBSD
organization (or any individual developer) poneys up the money for the
standard and signs the associated NDA, then either that developer or
the FreeBSD group as a whole might then be permanently barred from
writing open source code to implement the protocol, as a working
implementation could disclose protocol information covered as a secret
by the NDA.

  I'm sure that's *not* what you want to see.
