Mday: I use two connectors on two different lines. Long story short: I have three cat5 runs that have been terminated into rj45 jacks instead of wall plates due to location and no place to mount cleanly and hide. So when I need those connections, I just pop them out of their hiding places and slap a connector and patch cable (or dongle for laptop nic) on them. I still have anothe 1000 ft spool of cable lying around to pull from when I need new cables but for hiding in these high traffic areas that are only used during lan parties at the house, this was the best solution.
