In my experience, it matters a lot.

Unfortunately, that's impossible. The user always has to trust the 
server not to bind the IP address to the submitted dataset.

That would mean a single (or only very few) method(s) of aggregating, 
limiting the usefulness of the data.

If you're only ever concerned with single queries, that's fine. I 
imagined downloading data excerpts for a whole area that could be shared 
by different applications (so they don't need internet access during 
route calculation).
The querying user has to trust the server not to store its query 
patterns, BTW, so another case of "user has to trust the server".
