Mist of Pandaria addons - Blizzard enables UIs ( .LUA support)

Blue post:

Starting with the next Mists of Pandaria beta build, we plan to enable the use of UI addons. So whether you’re a savvy addon author or the most discriminating player, there’s no time like the present to start planning out your perfect UI.

Addon authors should also make sure to check out prominent addon sites such as WoWInterface and Curse for a chance to apply for a Mist of Pandaria beta key. These sites have recently been given a lot of beta keys to distribute specifically to active addon authors. We likewise strongly encourage authors who have access to the beta to start testing out and fine-tuning their addon updates in the beta as soon as possible.

If you use an addon and start seeing errors, try downloading the most recent version of it. If you are still having errors, you may need to turn off the addon until it has been updated.

So yeah, no more need to create custom fixes/repacks only to run your own AddOns anymore :)

How to enable your own Mist of Pandaria addons on any Beta Build

Main exe file: http://dl.dropbox.com/u/12654979/EnableAddons.exe
virus scan: https://www.virustotal.com/file/6ce4...is/1336224936/

source code: http://dl.dropbox.com/u/12654979/EnableAddons.cpp

Just run the exe and it will patch any open wow.exe it finds.
Also, note that the addon api is a bit incomplete atm (several functions seem to be either missing or renamed) so don't expect all your addons to run flawlessly.

Updated to a (hopefully) build independent version (thanks to TOM_RUS for the pattern)
Or if You prefer a permanently patched wow.exe look at this method (thanks to Ssateneth):
Credits go to TOM_RUS for new EXE's and oprime for pattern and patch bytes as usual.
