I would tend to align on the side of letting his domain sysadmin know (1st step)
of his activities (gotta love that logging...)

I would tend to view this as a somewhat obnoxious event, about on par with
banging at the firewall to see what ports are available for connection, and
then trying them out to see what you can find.  

IMHO, anonymous FTP is a public *service* you provide so as to limit or control
the amount or types of information you make available to the public.  It has
a clearly-defined directory structure, as well as (or should have) a clearly-
defined statement of purpose and controlled contents.

Channel-surfing for stray NFS mounts is not the same, unless those nfs 
mounts are there for public access.  NFS is not a common method of access
across the net (i don't think...correct me if I am wrong, but I am thinking 
of this in the same arena as anon/ftp) between non-affiliated organizations.

Just because I have data (by definition, as a net/sys admin, I do...)
does not mean that I am making it available to you for whatever you want
to do with it.  As a firewall admin, I have shut down all services I deem
as not being germaine to my connection to the world.  And, since I decide what
services I allow or not, and the user is probing a connection I am responsible
for, he/she/it should respect my wishes once they are made known to them.
It is not open for debate, especially with some net.critter outside of 
my jurisdiction.

Just my $.02, your mileage may vary.
