I do not know if it might help you, but here's my "temporary hack quality"
solution.
Assumptions:
Determine and mark 'good traffic' -- i.e. smtp, ftp, http, ssh, etc.,
everything which uses well known ports. Probably most people do it
anyway, at least to some level.
All what is left are P2P connections and some other misc connections.
A bit unfair for other protocol using non-standard ports, like Instant
Messenger style-software, and lots of other stuff. So here we introduce
a trick. IMs and other low bandwidth traffic will use small packets
( < 512 or even < 256), P2P will use maximum MTA available (usually
1500, but I've seen some using 576 packets, hence i treat > 512 as P2P).
Probably you've notices that I mention round numbers, as 512 or 1024,
that's because I use u32 for marking packets. How I do it, we leave
as an exercise to the reader. ;-)))
