Hi Ken,
It's very possible, and quite easy ... at least I think so.

For some odd reason I felt it easier to explain in html format that in 
normal text, so I wrote it into the FAQ.

But if I do a cut and paste, here's what it looks like.

    1. On the NFS server, create a directory where you want everything 
For this example we'll call use /export/localrepo
    2. On the NFS server, make sure createrepo is installed
       yum install createrepo
    3. On the NFS server, copy all your rpm's into that directory.
       It actually can be in a directory within that directory. They can 
also be link's, but those links have to be visible to the clients when 
it's nfs mounted, so sometime's it's easier to just do the regular 
stuff, and dump everything into the directory.
    4. On the NFS server, create the yum headers for that directory
       (For S.L. 3.0.x clients) yum-arch -l /export/localrepo
       (For S.L. 4.x clients) createrepo /export/localrepo
    5. Everything is now setup on the server On the client, mount the 
nfs directory, for our example, we'll say we are mounting on /mnt/repo
       mount myserver:/export/localrepo /mnt/repo
    6. On the clients, put this local repo into your yum configuration
           * S.L. 3.0.x - put the following on the end of /etc/yum.conf

[localrepo]
name=local repo
baseurl=file:///mnt/repo/

           * S.L. 4.x - create the file /etc/yum.repos.d/local.repo that 
looks like

[localrepo]
name=local repo
baseurl=file:///mnt/repo/
enabled=1

    7. On the clients, just use yum as normal
       yum update, yum list, yum install ...
