I just commited code to support 'runcmd' as a item in cloud-config.

This allows you to do have a cloud-config user data file that looks like
the following, and does what you would expect.

I am somewhat interested in getting runurl packaged into cloud-utils or
cloud-init so that you can skip the first 2 items in the list below.

#cloud-config
runcmd:
 - [ wget, -O, /usr/bin/runurl,
   "http://bazaar.launchpad.net/%7Ealestic/runurl/trunk/download/head%3A/runurl-20090817053347-o2e56z7xwq8m9tt6-1/runurl" ]
 - [ chmod, 755, /usr/bin/runurl ]
 - [ runurl,  run.alestic.com/demo/echo, ======== HELLO WORLD ====== ]
 - ls -l /root
