There is no scheme which can solve this in a similar way without
mandating lot's of things about the geometry description you use, or
incurring big overheads with clip planes e.t.c. That part is just not
there right now, and it almost defeats the purpose of CLIP mapping in
the first place.
In short you will have to solve your problem some other way until CLIP
mapping hardware is available (or pay a price for supporting that paging
model)..
This can be done using Performer, but the tools may be lower level than
you need, stuff like the LADBMS helps a lot with paging issues and
coordinate management etc. Double precision DCS' are being added to
Performer. That just leaves paging and that is in there and fairly easy
to use but load ballancing texture downloads to GFX could do with some
improvement.
Cheers,ANgus.

"One of the best-known folk theorems of software engineering is that
60% to 75% of conventional software projects are either never
completed or rejected by their intended users. If that range is
anywhere near true (and I've never met a manager of any experience
who disputes it) then more projects than not are being aimed at goals
which are either (a) not realistically attainable, or (b) just plain
wrong."
