Well, how about thinking of it this way:  Don't you just need to look at
the header of a packet before deciding where to send it?  Once you've
parsed the header and determined the routing of the packet, you can start
shoving it out the right pipe. :-)

At least... it would make the most sense to work like that ;-)

Regardless, there is still delay incurred at each hop (hello, digex/BBN
;-) albeit negligible...
