Hmmm.... I had a sense that no one is really willing to pay (in a 
traditional sense) for a cluster-on-a-DVD.  Well, maybe not this crowd ...

Note that RH and Novell view HPC as a very tiny market, as most in this 
market exploit the FOSS variants, and don't pay for the OS install.  So 
getting their attention will be at least a little on the hard side.

That said, there are some folks doing these things now for their 
customers, and supporting them.

Check:  Most unwanted ... some folks want to rip mp3's in parallel on 
their cluster?  I dunno ...

Check:  though define what "good" is.  xCat might not be everyone's 
impression of good.  Scyld does this as part of the distro itself.

You will get arguments here on this.  LDAP can be needy.  Even when auto 
setup.  I like it, but some insist on NIS, or others.  By default, we 
would do a ldap_pam/NIS for internal, and hide this from the end user, 
unless they really wanted to see it for some reason.

Separate application bits from the usage bits ... packages should be 
easy to install and use in the cluster (gui/cli/...)

Understand that some of the non-commercial academic closed/restricted 
stuff could not be done via a one-click due to their particular 
licensing agreements.  That said, the one-click could be done after you 
get the tarball (yeah, I said tarball, not RPM).

Noooo GFS.  Lustre is still too kernel dependent, though this is 
(slowly) changing.  You really don't want to go there yet.

Scyld will get you part of the way there.  Without being a commercial 
for them, others, us, you should see what you want, soon.
