thanks everyone for all the responses to my question.

i examined a few existing 'currency exchange rate' rss feeds but
solved the problem by instead doing a simple scrape from one of the
better-known financial websites.  (problem with this approach is, when
they change their website, my scrape will probably no longer work - so
some maintenance is required.) 

the problem with the existing exchange rate rss feeds that i looked at
is that they return more data than what i'm interested in, meaning
that i would've had to code something just to filter out what i need
anyway.

the webservices links are interesting. the way i'm using rss more and
more, i guess the line between webservices and rss is getting pretty
blurred. when there's interactivity (ie: between querystring
parameters passed to an rss feed) what is the difference between an
rss feed and a webservice anway?

btw, it apears that many of the webservices in those links are offered
only as 'premium' (non-free) services.
