I've seen patch to squid somewhere. The trick is to encode original requester information into new request packets. It can go into "priority" field - it is 32bit and is userspace-settable.
In Squid 2.5 you have the possibility to set TOS field with acls. This also works by calling setsockopt on the socket, changing it to SO_PRIORITY should take very little time
the only problem is that you will have to keep acls in sync with your tc setup. But it could be done. Also you can could read fw_mark (probably it can't be done from userspace => patch needed) on incoming connection packets and set it on outgoing. If you then set nf_mark in ipchains/tables and use cls_fw then all should work transparently ..
Although i like the idea and it would be more administrative overhead i would prefer the acl solution because probably more people would use it if you don't need to patch the kernel .. also there would be better chances of getting included into the main squid tree.
some day someone will write it. I need it too so that probably I'll spend some evening on it ..
Please tell me if you start on it so we don't end up doing the same work twice ..
