Do we provide a device that looks like a tty but is actually connected to
a USB pipe?

If not, are there major stumbling blocks or could this be done?  Even
perhaps just by providing a shim program that opened the USB pipe and
the master side of a pty?  I have a number of devices with embedded
environments that want to talk to their hosts by PPP over USB...
