Why do you think an alternative to event channels and grant tables is
needed?
Personally, I think there is a need for a more convenient _high-level_
API that more directly meets the split-drivers' requirements for
inter-domain messaging and bulk data transfer but this seems to me to be
another low-level API and doesn't seem significantly more convenient to
use than grant-tables and event-channels.
Is the n>2-way sharing feature the only benefit over grant-tables or do
you think there are other benefits to your approach?
