someone asked me this question. it seems reasonable, but i'm not aware of
any way to do it.

it is common for a user to leave themselves logged in, go to another part of
the building and try to login again. if they are already logged on
somewhere else they are told that they can't login again.

couldn't you prompt and say that you are already logged onto X workstation,
would you like to logout this connection and continue logging in here?

is this even possible?

are there any utilities to make this happen now?
