lhnz, I agree with you, completely. A designer should be judged on how they present everything. ALL resumes should be considered an example of how they design, and thus part of their "portfolio." I have been a art director and seen many resumes in my tenure. If an applicant comes at the problem from a fresh angle, it is welcomed with open arms. A good art director or creative director can work with this to fix the issue of contact info being buried and whatnot, as others have pointed out. This is a great place to start!
What possible ethical reasons do you have for trying to insure the purity of resumes and portfolios? Why can they not interbreed?
Portfolios authentically demonstrate ability in a way resumes cannot, hence either resumes should direct employers to portfolios or the designer should attempt to blur the forms (yes, the purpose of a design might be to add trustworthy information to a document in the form of visible proof of experience in the medium. As shown: an exchange of message clarity for message trustworthiness.)
