Do you have any thoughts on the size of this file?

Well, the prototype that I have half coded uses JSON if only because gson makes that choice
easy, but the last time that I said that big JSON is no problem was in Mahout.  After boldly
making that statement, I started trying to store models that wound up as 100MB of JSON which
good GB of RAM to parse.

My current, revised position is that serialization fashions will change over time and they
should always be pluggable.  As such, let's stay with what is traditional for a bit longer.
 XML should not have any significant size penalty if we both to GZIP the results and uncompressed
XML or JSON both win on readability which is the critical feature during development.

If size really is a problem, then protobufs or Avro is a better answer than JSON anyway.
