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...)
