rel=nofollow vs. robot.txt's content=nofollow

it has been determined that rel=nofollow (when used internally) can
actually 'evaporate pagerank' ([URL="http://www.bruceclay.com/
newsletter/volume69/nofollowtactics.html"]reference bruceclay.com[/
URL]) They basically say that if a page is PR10 with 10 links, and 5
of them are rel=nofollow, that still only 1 point of pagerank is
passed to the 5 "do follow" links (instead of 10/5=2 points).

My question is - does anyone know if using the content=nofollow tag in
the robots.txt file does the same thing?
