Easy fix for that. Let people steal from lockers.
option 1) If somebody hides near a locker and joe hologram comes up and punches in his code and if the lurker is watching him AND the lurkers peception is high enough, give the lurker the code. So when joe leaves, bam, instant access and less stuff to worry about being hoarded. This could already be in place, I don't know, I haven't tried it.
option 2) Letting players crack the lockers with security tech skill and a toolkit. More work for the coders but it would mean more chances for RP. Again this could be in place. I haven't had the guts (or tools) to try it yet.
also I think they do have a place with security and shit for lockers, at WSB. Its called a Vault.
