The other thing you could do is capture packets for the "ls -l" from the NFS
client:
   tcpdump -s 0 -w fifo.pcap host 
run on the client while doing the "ls -l" should be sufficient. (Doing it just
after mounting will avoid any attribute cache hit.)

You could then look at the fifo.pcap in wireshark (or email it to me as an
attachment and I can look) and see if the file type attribute is FIFO.
(If it isn't, then the NFS server is broken somehow.)

I just tried a trivial test (using a fairly old FreeBSD9 and a pretty recent
FreeBSD-head) and wasn't able to reproduce the problem.
For my tests, "ls -l" in the NFS client showed "p" and the "cp -R" worked.
I only have UFS file systems and tested with those.

I can only think of a couple of explanations:
1 - ZFS didn't fill the v_type in as FIFO. The NFS server uses the v_type
field to determine it is a fifo and not the high order bits of va_mode
(the S_IFMT bits). I don't have ZFS to test with.
2 - You somehow used an NFSv2 mount. (NFSv2 didn't have support for FIFOs,
if I recall correctly.)
You can check your mount options, including which version is in use via
"nfsstat -m" unless you have a pretty old system.

If you have a UFS file system on the NFS server, maybe you could try exporting
that and run a test, to see if it happens for a UFS export?
