IEEE Copyright Form: any bypasses possible?

Dear mathcopyright@,

Are there any news on the IEEE Copyright Form front?

I've had a paper accepted to IEEE ICNSC 2007, and they have the
following IEEE Copyright Form, which they indicate all authors must
complete:
	http://www.ieee-icnsc07.org/copy_right_%20form.pdf

One of the things that is interesting about the form is that US
Government employees preparing the work within the scope of their
official duties are also required to sign this form -- I believe that
it is intended that they sign it in two places, one to certify that
they allow for the transfer of the copyright to take place, and the
other to certify that the work is in public domain by US law.

Let me quote it from the form:

> *U.S. Government Employee Certification (where applicable)*
> This will certify that all authors of the Work are U.S. government employees and prepared the Work on a subject within the scope of their official duties. As such, the Work is not subject to U.S. copyright protection.
> (2)_____________________________________________________________
> Authorized Signature
> ___________________________________
> Date
> (Authors who are U.S. government employees should also sign signature line (1) above to enable the IEEE to claim and protect its copyright in international jurisdictions.)


My questions are:

1. What will happen if a non-US government employee (e.g. a student)
will put the signature in both (1) and (2)?

2. What if I put a notice "This paper is public domain" at the end of
the paper between Acknowledgements and References sections, and sign
only (1)? In such case, would it matter which step is done first?
Would the paper then be public domain?

Thank you,
