That patch already exists (at least for DIRECT hierarchies), see
Henrik Nordström's pages.

Yes, that is correct. Otherwise, your parent would have to forward the
address it is connecting to, too.

You are on the wrong track. Your TCP connection via a parent is to the
parent. period. The parent creates its own separate TCP connection to the
next parent, or the final destination; essentially the next hop along the
way. So, only the parent TCP/IP stack knows the address of the next hop,
but not yours. Therefore, in order to obtain that address, you would have
to look into the "Via" header, or invent a "X-xxxx" header of your own.

IMHO, I don't think it is worth the trouble. Just getting the IP address
for DIRECT/SOURCE_FASTEST/etc. suffices for my log file analysis thingies.
