If you've never seen it, you don't know what you're missing (a la multi

My understanding is that it's not trivial

I know that when I worked on AIX development (IBM's implementation of Unix),
we provided the virtual console via HFT (High Function Terminal). The
difficulty involved re-writing X screen device drivers that could understand
the HFT. It is not a trivial task, and eventually it was one of the reasons
that IBM gave up on them (AIX 4.1.x no longer supports HFT)
>Why do some people seem to prefer "screen" instead of virtual consoles ?
Screen was originally written back in the days of REAL tty's and VT100's as
the only interface to Unix. This obviously gives you multiple sessions/shells
per log in. One thing about HFTs, they weren't supported on dumb ASCII
(vt100-like) terminals - screen gives you that support.
While I still haven't installed NetBSD on my A3000, I await the IOmega Jaz
drive to do so, I cannot speak for the why (or why nots) of NetBSD.
