Hi John,

We implemented support for 50002 by ourself.

Changes are in our thredds-fork @ github: 
https://github.com/lost-carrier/thredds/compare/bfcad3b...b866259 - we had to 
change some versions numbers as-well to integrate in our nexus so cannot do 
pull request.

How to proceed with this?

Jochen
