[...] Does anybody know any userland tool, Linux kernel module, iptables/netfilter module, or whatever mechanism to change arbitrary headers of IP packets on-the-fly as long as they traverse the IP stack? Is there any known paper regarding this subject? [...] I thought it could be done in the "MANGLE" table of netfilter, but I found no TARGET that achieves that nor any documentation about altering arbitrary IP headers.
Did you check out the QUEUE option and the libipq API? With libipq you can inspect packets traversing the filter and change metadata or packet information. Cheers, Lynx.
