Re: [PATCH] implements 'firewalls' - ec2 security groups [revision 1]

Hi,
Sorry that I need to NACK this patch again, but I have same doubts as
with previous revision. Seems like you fixed safely..end blocks but:
* Please rename Firewall_Rule to FirewallRule
* Please move 'create/delete' rule to Rabbit
Otherwise this patch looks good and works flawlessly for me :-)

Also this seems like a formatting issue to me.
Dunno if you're using tabs instead of spaces, but please use spaces.
In Vim you can do it using:

I think this is OK, but we are including a JQuery library, so you can also
use JQuery helpers to manipulate with JavaScript. No coding doubts on this,
it's perfectly valid JavaScript code, but using JQuery will shrink it and make
it more readable (at least for non-javascript-gurus (like /me ;))

Please move this to Rabbit instead of using Sinatra 'post/get' helpers.
At least for parts where it's possible (like I know that we are not covering

I mentioned this in previous mail, but it was not fixed. If you have any good
reason to keep it as it is please tell me.
