aggregate NFS export

Is there any way in Linux to create an NFS export that appears to clients
as a single export, but contains more than one actual filesystem (export
a directory and other filesystems are mounted on subdirectories and are
seen in the export)? How about if those filesystems are mounted _after_
an NFS client has mounted this? An ordinary userspace file server (e.g.
FTP server, web server, RSYNC server) can see mounts on subdirectories
that happen even after they start running. Maybe some userland form of
NFS daemon?
