Found a very cool javadoc hosting service at: http://www.javadoc.io
Example: http://www.javadoc.io/doc/org.apache.accumulo/accumulo-core/1.7.1 Looks like it works from maven javadoc artifacts from Maven Central. Very very cool. Also, great for linking between javadocs. The first time you access a new artifact, it could take a few minutes to download, but after that, it's very easy to switch between different artifacts in the same group, and different versions for the same artifact. Could be a good way to link to the full javadocs, beyond just our public API (what we're not publishing on our site).
