I've been working on making the repository UI more intuitive. I wanted the UI to make sense at first glance. I believe I got the Subversion Realms working in an intuitve way now.

Notice that all of the repositories with the same realm are now under the same realm node. The Subversion Red-Book explains that repositories in the same realm should point to the same password and authorization file. I'm reflecting that best practice here.

Also notice that the second repository has a custom post-commit hook. This repository is using the rss hook that is in the "Subversion C# hooks" download page.
