Don't forget to draw arrows on your CAT5s so the data knows which way to go.

This month Underground Airlines is introducing its new Maxwell's Daemon Traffic Director
TM. Just install a Maxwell's Daemon Traffic Director

For a small monthly fee of $1000 Underground Airlines will ship you a regular replacement Daemon each quarter and you can return the used Daemon in the supplied packaging for refurbishment and feeding with our special grade Daemon food including Unobtainium and magnetic monopoles.
