Dirichlet supports JSON but uses Writable internally as do the rest of
the clustering algorithms.

The idea behind MAHOUT-510 was to try to standardize serialization
mechanisms as much as reasonable. It would be counterproductive to remove
one and add another, I think. There was some support for using Avro for text
serialization instead of JSON, even though that has the same issue -- so I
think Avro is somehow considered a better idea than JSON.
I contend that it'd be nice to just deal in serializing stuff to files via
Writable; the use cases for serializing to strings, or passing in memory,
seem deprecated, which is the last use case for JSON/Avro at the present
time.
I still suggest step 1 is to try try to change dirichlet to make a few
classes Writable and pass the model that way. Then we'd be done.
Then, hey, think about reasons Avro is needed.

Protobufs are a good choice :)
