That is where a middleware like OpenMAMA comes in handy - OpenMAMA
(with a messaging broker or multicast solution like avis or ZeroMQ
underneath) can distribute the prices around on your local network for
different users and applications.

Then you just need some feed handler(s) to suck the prices from Google
or another source and transmit them into the OpenMAMA framework.  You
can change the feed handler when necessary without having to change
all the code that consumes prices.

The description looks very similar to what I had in mind, but I notice
that is in Python.

For OpenMAMA, there is a C++ and Java API and I notice that
LibreOffice offers both C++ and Java extension writing tutorials.  Can
you make any comment on which might be the better choice and any
example in one of those languages?  I suspect C++ would be the better
choice for performance.
