The AMIs were noted in the release notes and marketing material around 
the release as a feature of the F14 release. To me they're effectively 
being touted as an official release media and as such should be subject 
to the same processes as the DVD or LiveCD images.

While I agree that it's great that Rackspace and Slicehost have been so 
quick to get images up it's important to remember, at least in the case 
of Rackspace, this is primarily down to the goodwill of one of their 
employees who happens to be a Fedora enthusiast. Unfortunately we can't 
rely on this being the case at every cloud provider :(.

I would however think in future we might like to make some more noise 
about the presence of images we are aware of on other providers - 
obviously this would be at odds with my first statement about subjecting 
images to the normal rel-eng process. This is where we have a difficult 
balance to strike as some providers may not even make it an option for 
us to supply our own image.

The reason Amazon are able to take such a hands-off approach is that 
they are seen as the biggest player in the public cloud market (rightly 
or wrongly) and it feeds into that if they are the only provider we 
market ourselves as available on.

FWIW I am aware I am still just shooting from the peanut gallery here, I 
do still hope to be able to contribute to the Cloud Guide in the future.
