The main difference between PuSH and a basic RSS feed is that with PuSH you actually "push" out the information to Google exactly when it's published, instead of waiting for Google to crawl and discover it whenever. Even if another site is also getting your PuSH besides Google, they simply cannot scrape, publish and then get credit for your content earlier than the time and date when you published.
I've read that one reason that Blogger sites can be so problematic when they scrape your content is that PuSH technology is integrated into Blogger by default. This gives those sites an unfortunate advantage, as I see it, unless you also use the technology.
The site I've been talking about was built on a common CMS, and most CMS these days have plug-in modules available for PuSH. Those modules allow the site's server to be its own hub. For example, Wordpress [wordpress.org], Drupal [drupal.org] and MoveableType [plugins.movabletype.org]
I grant you that if you're not using a plug-in for a common CMS, then this technology can sound pretty geeky and confusing :( - howevder, the programmer I worked with said it was a lot easier than he thought it was going to be.
