The danger of accidental and/or malicious abuse, not to mention what happens when the bug is "fixed," would seem to argue against the scheme in the first place. Several of us have been scratching on some sort of gateway requirements model which, if it were adopted, might preclude your scheme in the interests of robustness. Your comments on Appendix A of RFC-981 would be much appreciated. Dave -------
