Thanks for the answer.

Errr, >>1 GByte just to provide an interactive GUI to something like 5
users and doing some inter-application communication - I wouldn't really
consider that as nothing. Especially not if it scales hyper-exponentially
with the number of users and/or the data volume. After this first
application, we expect to be able to use the same application for sites
with something like 100 concurrent users as well.

The point is that this can be worked around by retrieving the data in
background and "caching" it in a local database. Sorry that I didn't
mention this. In fact such a database would have to be part of the
application, as some of the communication with other applications will have
to be offline, in "batch" mode, in both directions (get as well as put).

Hmm, are cs students THAT expensive even as interns? >:->

None of them has ever mentioned Python at all. >:->
