The code is not open (despite the OpenDLM name :/

Yes. But it wasn't worth thinking about too hard because afaict there
were no reasonable distributed lock managers available.

The gborg-based replication project probably needs a distributed lock
manager. Not sure what it uses currently, and it looks to me that IBM's
contribution stalled out for the last few months. There is a little
activity on their mailing list but they missed an "any day now" release
back in October or November...
