I think so.

The hardest part is if you want to export a filesystem that also has
non-nfs users--in the kernel it's much easier to maintain consistency
between local users of the filesystem and nfs clients.

If the server has no local users, then userspace may turn out to be
easier.

In that case you might ask why the server needs a real filesystem to
export at all--in theory it could maintain all its data on its own.  But
I suspect if you try that you find you're reinventing a lot of wheels.
