How do I change to NFS version 3 so that other UNIX variants may access my NFS share on my Fedora 17?

Bear in mind if they are *not* equally trusted they can destroy you data and 
files. Trust isn't limited to "not evil" it also means "not incompetent" as 
well. How do you tell if it mounted nfs3 or nfs4, I had similar problems with 
mounts failing until nfs4 was explicitly forced, so the assumption that it works 
out of the box may not be (probably isn't) correct. I have seen this on fc16 and 
17, skipped 14 and 15 on my servers.
