Sorry for joining the discussion so late, but what special key combos
are we talking about? And what changed in the kernel?
I agree that it does sound absurd to require root privs - and of course
it goes without saying that the IDE _cannot_ under any circumstance be
distributed to run as +s, it just cannnot happen, period.
These privileges that we are talking about, are they transferrable
between processes? In that case, we could write a small setuid wrapper
to setup the terminal, then exec the IDE without privs.
Under any circumstance, if there really isn't any New And Improved way
to do this sans root, we should bring it up on the kernel mailing list.
I can do that, if need be - I'm always quite interested in security matters.
