Scratch

I was thinking:
What if it were possible to create a text-based programming language inside of Scratch called Agent? It would be written and understood by Scratch. Maybe it would be written with lists that is then interpreted into something onscreen.
I've thought of some ways it can be applied with Scratch 2.0.

Cloud variable editing:
Found a glitch after you have posted the project and it already has 500 views? No problem! Open up your project (Written in Agent) and modify the script using cloud variables.

All they would have to do is download the original Agent project and write it in there and post.

Plugins:
People who want more can easily modify the code themselves without having to download.

More freedom:
New commands could be understood, each functioning better than Scatch could.

DANGERS:

The script could be hacked more easily and the entire project trashed. This could be solved with a password or hashing.

Sprites could not be edited with Agent.

What do all of you think? Is it something we need or should be working on? Or am I just rambling?
