There was once an "External Collection", which can still be found here:
http://www.xworlds.com/metacard/

That supports DDE (Dynamic Data Exchange) on Windows, and that might be 
exactly
what you are looking for, although i do not have the slightest idea how 
that works :-)

The collection is supposed to be free nowadays and you should contact 
RR to get
a free license key...

Hope that helps...
