Suggestion: category- or channel-specific nicks

On several (RPG) servers where I have multiple different characters or identities to have I might need to change my nick to clarify my role in that category (game) or channel. For example on our Lancer campaign I'm "Kim | Farshot" to clarify what my character name is, and then on Star Wars campaign I'm "Kim | Kusuri". However, these campaigns are on our shared server (to make it easier to match new campaigns with players) and nicks being server-wide might confuse things.
