Rick, Thanks for the suggestion, but we need a wider range of measures than those supplied here, so I'm following the tinkerpop team's lead and implementing the JUNG Graph interface, but using traversers under the hood. JUNG has a much fuller set of algorithms and seems to be more actively supported.
However, we'll be dealing with network data that have real-valued covariates, and we'd prefer not to throw away information.
