Well, you can also create additional query server on each of the 
external servers, which then passes each query to their respective local 
tracker and sends the results to the client library. This lib would then 
need to merge the results and provide them to the application using the 
data. Only possibly difficult part would be in sorting the results. 
Should be a nice exercise to do it.

Sorting is the difficult part. However, if you are making metadata 
queries, the result merge should not be too difficult.

Indeed. And not a bad idea to work on such a thing.
