So, EC2 doesn't allow (this week) the specific injection of files into  
instances.

It does allow placement of up to 16k into a location that can be  
fetched by instance upon boot.

With EC2, we could 'fake' file injection, by only having the driver  
inject it into the instance boot metadata.

It'd be up to the image to actually do the pull at boot time.

I think this would allow supporting this functionality, and not being  
limited by what EC2 can (or can't) do.

A 20-line bash init.d script could be provided for people using EC2 to  
enable pulling from the metadata at boottime and injecting the file(s)  
locally.

Ultimately, "injection" is only partially defined to mean "push as far  
as possible for this provider".  And I think that's fine.
