Tool for source routing

Can anyone suggest a good tool to perform ip addr spoofing via source routing?

That is, it should replace the source addr with a spoofed one, and add the
real one as a source route. It must also forward the recieved packets,
since their dest addr will be the spoofed one.

It should ideally be able to sit in between other apps, both ones that use
connect() and ones that use raw sockets, and modify the IP packets to
source route. This would allow use of preexisting tools without
rewrite/recompilation.

BTW, I'm mainly interested in using it on Linux 2.2 systems. If this can
be done with ipchains, could someone suggest how?
