I think a lot of the concepts from traditional publishing can be translated to this sort of online publishing. Once again, I think if it was easier for a researcher to self-publish and get peer reviews then to go through an old school publisher, then they would do it.
For an example, here's the transfer form for the American Chemical Societies journals: http://pubs.acs.org/page/copyright/journals/index.html (the ACS has historically been one of the bigger roadblocks, along with Elsevier, to more OpenAccess reform).
Many people work around this by self-hosting a very similar paper, rendered from the same LaTeX sources, but without the IEEE chrome. IEEE usually turns a blind eye.
However, you are definitely not allowed to post the IEEE rendered version.
I extend your quote from your cited source:
"6. Personal Servers. Authors and/or their employers shall have the right to post the accepted version of IEEE-copyrighted articles on their own
personal servers or the servers of their institutions or employers without permission from IEEE, provided that the posted version includes a prominently
displayed IEEE copyright notice and, when published, a full citation to the original IEEE publication, including a link to the article abstract in IEEE
Xplore. Authors shall not post the final, published versions of their papers."
