Folks,
Per  http://developers.slashdot.org/story/12/02/01/1429229/wikipedia-chooses-lua-as-its-new-template-language  and 
http://www.mediawiki.org/wiki/Lua_scripting, mediawiki will embark on this major effort.

How will this affect SMW and the satellite extensions that revolve around it? 

Best,
Joel
