Hi Terry
This is news to me as well, although I don't do financial systems at the moment. Isn't the problem with Bloomberg that if you want them to do something specific for a page, they 'host' the calculation on their server?

I assume you're talking about accessing data from their systems, rather than contributing it back again?

It's a long time since I looked at any of this, however isn't there another issue with Bloomberg concerning the way they store data and decompress it on the fly? Reuters has a similar compressed and re-compressed format I think?
