Thanks for bouncing this - seems it passed us all by when you first posted. Is the formatting:
- conditional (colors based on values, etc)
- graphic (logos etc)
- symbolic (e.g. Sparklines)
Is the output to be:
- queried interactively?
DataPump may not be the whole answer, but the new Datawatch Server combines this with The XSLT options in Content Server, as well as the dashboards of the Panopticon product, so might be worth considering.
If you want advice from someone who's not trying to sell you the technology, please drop me a line.
