Well the whole idea is to have stable, reliable interfaces between the
modules. So if you want to work on / build the latest WUI code you can
download the latest pre-built managed node binary from the ovirt.org 
website, and not have to worry about building something you're not 
interested in changing. In the scenario where you really do want to build
all 4 pieces from scratch, its really not that hard to type 'build' in
each of the 4 directories. If it was too troublesome, you could even 
create a shell script 'build-all' to run

 for i in node server appliance ; do (cd $i && build ) ; done

It would be trivial to make the auto-build output available too - we could
simply add a post-build stage to it which publishes nightly RPMs onto the
public oVirt website FTP area, so latest binaries are always available
for working against, 

As a comparison - consider someone working on Fedora - they don't want
a build-all script for everything in Fedora - they only care about building
the package they're playing with. Or someone working on virt-manager - they
don't neeed a 'build-all' script which builds Xen, libvirt, and virt-amanger
all in one go - they simply use a pre-built Xen & libvirt binary, and only
focus on the bits they care about.
