You're correct to say that this is a gap in the existing set of open source
licenses.  What I would do if I were you is to construct such a license
using the MIT license and the attribution clause you want, carefully
tracking the language in the GPLv3.  Then follow the process "For Approval"
at http://www.opensource.org/approval .  IMHO you can reasonably ask for the
outside legal review to be waived, given the simplicity of your license.

Sir, I quite agree with you, but what are we two against so many?
