That model works fine for:
1. Someone only working on the Server and can just use last available 
version of Node
2. Someone only working on the Node and can just use last available 
version of Server

What about:
Someone working on integration between Server and Node and needs to build 

build-all cannot be trivialized into a for loop that does build on all for 
separate git checkouts.  It's more involved than that.  We use a common 
tmp directory for yum cache to build the node and appliance.  And RPMs 
generated from ovirt-node and ovirt-server would need to get placed into 
that cache for build of ovirt-node-image and ovirt-appliance.

build-all.sh could be used as we use it now even with 4 separate repos 
underneath it, but the question becomes 'what repo does build-all.sh live 
in?' given that it is fairly complex.  Hmm.  Perhaps we need an 'ovirt' 
repo that contains build-all.sh and things like ovirt-release RPM build.
