RE. issue 2) and 3) I just thought that data cubes an open, but standardized format could help - not only in the financial area: I found RDF data cubes ( http://publishing-statistical-data.googlecode.com/svn/trunk/... ) perhaps being a part of the solution there, with the value add that you could easily connect different data source using their semantics.

(liked the "basecamp for analytics" point)

Yes, an RDF format looks like a good solution. It appears that RDF is quite supported in python and that it also abstracts away persistance (http://readthedocs.org/docs/rdflib/en/latest/persistence.htm...) in a way. I ll look into that, thanks.

If you like the basecamp idea for analytics, I am kfk on github, I am doing some demos to get an idea.
