I'd go with a minimal header in text files stating that the file is under AGPL, ast stated in the COPYING file included in the package.

Doesn't appear to meet the requirement of the license, though.

Yeah, it actually looks like you're not permitted to do so, and if you want to do so you should create a new license - http://www.gnu.org/licenses/gpl-faq.html#GPLOmitPreamble
Bogdan
@Robert Harvey but what requirement.. can you point it to me? Also how would you license binary files e.g. .png, .ogg, etc. that come as a part of the application?

@Bogdan the link you posted doesn't answer my question, it discusses possibility or rather lack of shortening the license itself.
