"the main goal of the workshop is to allow the Lua community to get together and meet in person and talk about the Lua language, its uses, and its implementation.... We shall have a plenary talk by Roberto Ierusalimschy (Lua's chief architect) and several contributed talks.... If you'd like to speak at the workshop, please send a tentative title and a short abstract to the organizers."
If you think it would be useful for Wikimedia to make an appearance, go ahead and submit an abstract or suggest someone to go.
And financial subsidy may be available for you to go: https://meta.wikimedia.org/wiki/Participation:Support
