All: I spent quite a bit of time researching the demise of Lucene.Net.Distributed (now Contrib.Distributed), primarily looking at SVN tags and the mailing list. I gather that it was only ever a reluctant feature, which had few users, went unmaintained, and thus was quietly dropped during the transition from 2.4.0 -> 2.9.1.
I noticed that much of that code remains in src/contribs, so I attempted to restore it back to its former state. To make a long story short, I have reconstructed solution files, project files, tests, etc. and have migrated them all forward to use 3.0.3 trunk. It now builds and (nominally) runs. It does not pass the tests since the Soap formatter does not support generics. I did not make any modifications beyond those needed for reconstruction and migration. I am considering migrating this to ServiceStack, or WCF, if there is interest. However, some may be interested in playing with it as-is. I'd be happy to submit a patch against trunk, but I'm not sure of the protocol for that (e.g. send it to dev list, private email). The patch currently weighs in at 344 KB zipped/~3 MB unzipped.
