Another question is which terminals should actually be supported. Many
of the ones you mentioned have died away already. I am aware of the IBM
3270 family and the DEC VT100 family having a long and healthy live (to
Michael Everson: those might indeed still be around in a hundred years
from now, we will know after Y2K), but much of the rest is probably not
sufficiently mainstream enough to deserve consideration in Unicode.

Do you have any form of data on the terminal emulator market regarding
more exotic terminal types? Are there really more than a few hundred
people out there who use applications that depend on a terminal type
radically different from a DEC VT340 or a IBM 3278?
