Currently such functionality is not part of AWIPS2, but yeah, I am optimistic 
that such a thing *would* work.  I would like to investigate it, for sure.

I don't understand what your interest in the CAVE client running on a VM has to 
do with distributing the regional ocean model data to forecasters.  

On the topic of external model data, I can't say much.  I am only ingesting IDD 
data via the LDM.  The LDM works really well for this purpose given the 
"edexBridge" program that is bundled with awips2-ldm - each product filed to 
disk by pqact also has a message sent to the Qpid message broker which alerts 
the EDEX ingest JVM that a product is ready for decoding.  I have seen a script 
included in an earlier version of AWIPS2 which was designed to mimmic a live 
ingest for canned data, and it sends a message to Qpid just as edexBridge does 
with the LDM.

I'm sorry I can't say more, I haven't explored this method of data ingest 
enough to give you a more thorough answer.
