i don't think that these two URIs would ever differ. based on my 
scenario (providing aggregated feeds as a way to specify queries across 
a number of feeds), there are are reasons for the IDs:

- even if the aggregated does not contain any entry of a feed it is 
aggregating, the <link /> still specifies that this feed is contributing 
to the entries available through the aggregated feed.

- in the query on the aggregated link, the IDs are used in the query 
itself to specify the entries a client is requesting, such as "i am 
interested in all entries from 'feed1' where the title contains the 
string 'atom'."
