Well, you need to be able to write a C extension :-(. I kinda wish
that were not a requirement, but in practice I think the main audience
is people like PostGIS, who already cleared that bar. I hope that
we'll soon have a bunch of examples, like those in the 0004 patch,
that people can look at to see how to do things in this area. I see
no reason to believe it'll be all that much harder than anything
else extension authors have to do.
