A more basic question is whether the person requesting the information
should be able to just get some subset of data and perform unknown
manipulations on it.  Do the requesters really understand the data?
What are the business uses they will make of the data?  What
validation will be done of their extract criteria and subsequent
calculations?  This may be the way to go depending on the requesting
community but the difference between almost right and right is a lot
of attention to mind numbing detail and obscure rules.  Almost right
may be more than good enough for the purpose but the question needs to
be asked before the genie is let out of the bottle.

Also what are the security implications of being able to download that
much data?  It will fit on a USB key.  Will there be an audit trail on
the downloads?

At this moment these things are not a problem. In our current web app
we also provide them with this data. They work with it... The only
thing is we do it now with EntireX and we call it repeatly (using a TS
q. to store the data temp.). But we are trying to move away from
EntireX and make it webservices. I can do it in the same way, like
request the same service for 3 times (then I can get 2100 records) but
I prefer to do it in one request.
