[openstack-dev] Request for feedback - Nova image building proof of concept

This entire concept made me do a happy dance. :)
The idea of an end-user being able to compile a standard automated build
script for their operating system, to upload it, then to select it for a
new instance would be a killer feature. While instance builds may take a
bit longer, the customisation power it puts into their hands at such a low
barrier to entry would definitely make many of our customers happy.
If the access to ISO's and build scripts could effectively be managed in
the same way as images in glance today then it'd just be one more step of
The final awesome, of course, is to allow bare-metal provisioning - so the
merging of some of NTT and Triple-O's work would be needed.
In case you hadn't noticed - love your idea. As soon as I get a moment I'll
be trying it out and providing more technical feedback.
