Sure, ip-options bits were/are allowed for LSRR/SSRR, which as you said
below is disabled for a multitude of reasons on many/most/all (?) large
parts of the Internet for many reasons, not the least of which is
performance penalties. So, aside from the 2 examples routing ip has been a
hop-by-hop destination based problem, source addresses (even with
LSRR/SSRR I believe) has little to do with the equation.

I could be wrong, I am just a chemical engineer. If this was a
distillation column or a raction vessel I might be more sure :
