[Pgi-wg] Promised document

[Morris Riedel]

Wow,

  and so we have the perfect base (IDL) for two non-interoperable
solutions/renderings of it (front 1) and (front 2)!

And I remember this from somewhere in the past...

Can we go back to UNICORE UPL and gLite JDL then... only defining
data-structures doesn't help on the real wire and thus does not really
enable interoperability.

We failed in OGSA-RUS in this approach and my experience in using different
DRMAA implementations together wasn't that much better (only slightly
because of language-based renderings...)

Take care,
Morris
