I believe your good intuition.
As HBase and Hadoop regarded as a valuable project by cloning Google's
papers,
our BSP package also have a opportunity to become a outstanding project in a
similar way.

Let's discuss pregel paper in detail if the paper is released.
If possible I want to make meeting in offline as well as online.
In addition, I think that we first take into account performance issues
before discussing heterogeneity and fault tolerance (just my opinion).

Maybe, one of my collegue has scheduled to attend the SIGMOD 2010 as an
author (regular paper).
I hope He will give us good information.
