A virtural machine (guest) under VM could have multiple 3270-style
terminals attached "directly".  You can get to these 3270's via the DIAL
command at the VM logo, or you can have the guest operating system
claim them directly when it is IPL'ed.

One system that can run both as a VM guest and support mutilple 3270's
at the same time is MTS (Michigan Terminal System).

I supposed the reason AIX isn't supporting mutliple 3270's is because
its implementor had choosen not to.
