you could use robots.txt to exclude the iframed document from crawling.

#1 technically speaking, should an <iframe rel="nofollow" do the trick or no ?
#2 any assistance using robots.txt to exclude this particular iframe banner is appreciated. Just to give me an idea , so I could do the same with the others. I never knew you could block them through robots.txt Maybe ur just talking about the URL and not the whole iframe code? anyway, code below :
<iframe width="300" scrolling="no" height="250" frameborder="0" src="http://ads.mysite.com/ads/juggcash_inserts/300x250_1_0_lp.php?nats=NDg0MDYwOjM6NDE" allowtransparency="true" marginheight="0" marginwidth="0" name="" rel="nofollow"> </iframe>

something else I also thought of after submitting that...
Is that Robots.txt kind of works differently than rel="nofollow" i would think.
PR might still be able to leak onto the external link if it's just Robots.txt'd.
rel="nofollow" specifically tells google "i don't want PR leaking onto this external link".

iframes don't pass PR - only anchor elements (and if used properly link rel canonical elements)
that's because an iframe isn't considered a link between web resources.

i'm guessing the rel nofollow on an iframe won't validate but it's more useless and irrelevant than harmful.

making some assumptions about your url structure - i would suggest blocking any access by googlebot to the ads.example.com hostname or at least the ads subirectory.
the robots exclusion protocol is pretty simple:
The Web Robots Pages:
http://www.robotstxt.org/robotstxt.html [robotstxt.org]
Robots.txt Specifications - Webmasters — Google Developers:
http://developers.google.com/webmasters/control-crawl-index/docs/robots_txt [developers.google.com]
Block or remove pages using a robots.txt file - Webmaster Tools Help:
http://support.google.com/webmasters/bin/answer.py?hl=en&answer=156449 [support.google.com]
note that robots.txt can and should exclude googlebot from crawling the (iframed) resource but G search may index the url without crawling the content...

thx dude, yea I kinda forgot that we can't robots.txt external files...so i'd have to iframe it locally first, and then robots.txt those files. (directory)
I did 'not' know that iframes don't pass PR at all though. example if my iframe had <iframe=src="http://ads.externalwebsite.com
I would always feel some PR would leak. But i'm guessing your saying no, so i'll believe it.
