Had some events unfold in a dream last night that I figure would make for an interesting run, I know it would be a long time before I host a game so I present this as a gift to the dumpshock community. Forgive me if this was already done already.
Basically there is a facility which is working on some very secret stuff, so secret they have put into place the following measures.
All employees are outfitted with some memory altering/redirecting ware such that a "knowledge chip" is inserted upon getting to work and removed when leaving. The ware redirects everything that is learned to be recorded on the chip and not the subjects memory. This could also be interpreted by being jacked in and stored on a server and not actually a chip. Either way basic concept, memory/knowledge related to work stays at work and if everything is working properly will not leak into anything the subject can recall outside of this environment.
I can see this being utilized in some confidential environments where you don't want the risk of a grab & mind probe or other bean spilling tactics as the subject literally does not know anything that they do at their workplace. This also works well to have multiple shifts working on the same project as when the person tires, the next guy picks up where they left off. This would still require that the person has technical ability or else there is no growth on the information.
Have fun!
