greynet
n.— «FaceTime categorizes IM applications as “greynets”—a term for a class of applications that enter the enterprise via the end user and exhibit evasive behavior over the network (including peer-to-peer sharing, VoIP and Web conferencing applications). The problem with greynets is that their providers’ primary objective is to ensure usability regardless of location, whereas a priority for IT managers is to control everything their users are doing on the network.» —“IM: Real-Time Problems” by Cory Levine Wall Street & Technology Mar. 21, 2006.
