Thanks for the reply. Your vision sounds pretty good,
assuming the non-Unix platform vendors provide that (new)
capability in the future. Given that Microsoft is somewhat
involved in the IPP process, then perhaps such capabilities
will appear before the end of the millenium. (no joke)

A quick aside, your Unix example is quite nice, I agree.
However, those not familiar with Unix (and all the common
variants) should understand that your example is actually
not valid, at least from stock O/S vendors.

Perhaps you were thinking of the capabilities provided by
Patrick Powell's fine LPRng suite, which exposes network-
attached printers using standard hostname conventions
(rather than sysadmin-defined printer objects on the local
