Yes, Cairo looks nice. I hope it gets beyond the "glacially slow"
performance this side of Etch's release.
With regards to IPP support, this sort of thing has been requested for
Xprint too, and I've started looking into doing that. Would you agree
that Cairo should be engineered to support the Free Software Group's new
OpenPrinting API (PAPI)? It's a superset of IPP, allowing support, for
instance, for LPD systems if CUPS happens to not be used.

It will be interesting to see these developments in action.

Your reasoning basically makes sense to me. I'm not really in a position
to argue for or against the unified server, but those who want to know
more can check the xprint and xorg archives, see

Yes, I think that is reasonable.
