Can I display different versions of a page based on http referrer without risking ban?
What difference between the two versions would be acceptable?

Anything not deceptive to the user would be my guess, not baiting and switching content.

I've been running http_referer based cloaked page for more than a decade for a competitive area as part of a test of this very question. Result: no problems; top ranking.

Be aware that many legitimate visitors do not present a referrer - the data is suppressed by some ISPs, by some "internet security" software, or by user choice (browser settings).

That's good, isn't it? It means that the version seen by robots will also be seen by perfectly legitimate humans. If all humans had referers*, the no-referer version would only be seen by robots-- and that would be a problem.
* Which they wouldn't anyway. What about bookmarks and type-ins? Those should be the visitors you love the best.

getting slightly off-topic, but...
email clients and non-browser web apps such as twitter apps won't send a referrer.
