Yea, I went to: http://sources.redhat.com/docbook-tools.  It had a 
documentation link to the oasis-open.org site you referenced, so I 
incorrectly assumed they were the same.  Either way, that's the package 
supported on Gentoo, so I simply marked nbd-2.7.1.ebuild as dependent 
upon it and it'll just all work out in the future.

BTW, this ebuild is now live on Portage rsync mirrors, it ended up 
looking like:

*shrugs*  It's done now =)  nbd isn't the only package to do things this 
way.

Incidently, Gentoo just marked the 2.6.6 kernel-headers as stable, so 
the patch to copy over nbd.h is not really needed anymore.

That was from the previous ebuild, I didn't change it, not sure if it 
was needed..

Cool, I'll give that a peak.  I'm just starting to set this all up in a 
lab environment.  My ideal use for NBD is to create a redundant "network 
head" to my own AS within a datacenter.  That is, I get 2 or 3 redundant 
network drops to different CARs which feed into this redundant mesh.  I 
want to have each drop go into a different server, but I want all the 
servers to share the same basic filesystem and for that filesystem to be 
automatically rebuilt when a one of the heads fails.

Yea, it's gonna take some R&D, I'm still looking at the Linux 
High-Availability project and I might have to use some routing daemon 
ala Quagga to handle some of the network routing/failover stuff.  I 
originally had this idea awhile back: 
http://www.clanhk.org/modules.php?name=Forums&file=viewtopic&p=3823  
It's taken me awhile to get my head around it.
