Especially those of us who have used it Xenbus :-)

My fear with using PCI is that it is a short-term remedy that we might
find ourselves locked into once we start, and there are lots of things
that will not fit into the PCI model. So we would have picked a
short-term, expedient approach that works for simple cases that breaks
interesting uses.

It's happened in other projects ...
