Good point.

OTOH, it's not only GFS that is or should be involved. In fact, I see 
the following group's involvement:
- GFS
- WS-Naming
- JSDL
- DMI
- HPC
- GSM

I would like to know if there are enough resources available to get all 
these groups together in an inter-group F2F to wrangle this issue?

Cheers,
Michel
