Is it possible to mount a fs via nfs, and then reexport it via nfs?

No.
The protocol doesn't really support it, and the (Linux-kernel)
implementation definately doesn't support it.
I think the user-space nfs server can do it. It has other problems,
but it might work for you.

definitelly the kernel implementation cannot manage the loops a re-export
would imply.

yes, you have to run both rpc.mountd and rpc.nfsd with the -r option.I
used this one year ago, and it was really stable with 10 nfs clients
(physicaly the partition was on an AIX server, mounted on a linux server
and then re-exported on many linux clients), but the physical FS status
could not be really coherent in front of what the nfs re-export server
thinks it should be.

Currently, no.
With some restrictions, it could be done. For any given IP address,
you could export or re-export filesystems from _one_ source server.
Anything more is like trying to cram N+1 bits into an N-bit sack,
and no you can't assume the bits are compressible.
