This is only a problem with samba, but not with WebDAV as 
http://pepespc:6060/ is a correct URI.

I havn't said anything about NFS (I don't like NFS except on 
server-to-server mounts) but any user can run a smbd daemon with his own 
configuration and port (changing the port is of course not compatible 
with any microsoft product, but they can still access it through a 
WebFolder with no problem). I still think that a 
smb://pepespc:7070/SHARE is not a bad idea for inter-gnome operation.

What I say is that relaying on a systemwide dependent filesharing would 
not be my choice for security on a network deployment.

Well, neither SLP nor libslp are GPL but a MIT/X/BSD style license:

http://www.openslp.org/license.html

And yes it's from Caldera/SCO :-S

I will take a look on it this week and try to come back with some proposal.
