Now it is EC2-only but Google's ComputeEngine was on the horizon.

You run the tool with the data (AMI IDs, region, arch) and get the
result in a meanwhile. It can be fully-automated once we have this data
announced via fedmsg or in any other automated way (now I just read
mailing list and if there are any images announced by Dennis I run the

Well, it depends on what's our future plan. IMHO once we have images
announced via fedmsg we can have all basic things covered by the existing
tool (and I'm definitely in for integration and support process for the
tool) and it won't take us long to set everything up. With regards to
Taskotron I want to know more on how this 'cloud integration' is planned
as (if I'm not mistaken) there's no code written yet. If merging here
seems reasonable then I'm in. I'll try reaching out to Tim & others on
fedora-qa-devel list.
