You could do something like:

 - if there are 7 or fewer suggestions, show them all.
 - if filtering reduces the list to 1 to 7 suggestions, show those.
 - if there's some way to prioritise the filtered list, show the 7 best 
   results from the filtered list.
 - otherwise, show everything.

Exactly how the filtering is done can vary, in a way similar to how 
autocomplete dropdowns in browser location bars have pretty involved 
heuristics for figuring out how to filter to a few results.

No, I'm saying it should be done using XBL or its successor.
