I have a PhD in chemical engineering, but not a PE, since I didn't go the industry route. I wouldn't feel comfortable calling myself an Engineer without it, and that was the attitude expressed by my professors and cohort coming out of undergrad.

It's my opinion that the title "Engineer" should be on par with things like "Doctor" or "Lawyer". It should require certification and there should be consequences for claiming to be one if you aren't.

I don't think anyone would get in trouble for job titles like "computer doctor" or "network protocol lawyer". Practicing medicine or practicing law (or in some cases, practicing as an engineer) without the required qualifications, regardless of job title ... different story.
