Comment (by starlight):

 How about this?  A hashlimit rule that establishes a maximum byte rate out
 to any /24, /22 or such.  My point is netfilter allows rapid what-if
 testing of various rate limit strategies, up-to and including HTB ingress
 schemes with IMQ and arbitrary schemes with nfqueue.  Dirport queries are
 clear-text, it should be manageable to distinguish between compressed and
 uncompressed queries and mark connections accordingly.
