Hi Sam...!
Doesn't this Hoplist idea tie up the Site, and the single Port address, 23456, to the folks involved in the Hop...?
Note that WS Pilots have
three port addresses, 23456, 23457, 23458, one or more will often contain a particular Server's Hop, which other flyer's should really avoid unless they are involved in it...?
The remaining port address(es) can then be used at any time for the occasion flyer, or group of flyer's without interfering with others...

...!
What do you reckon...?
Paul....
