I'm worried about creating a .mem for it to work on my computer... And 
if people will want to experiment it before TL2009, they will need to 
create a .mem too.

LuaTeX with mplib doesn't care about the name of the executable, the 
.mem file is a variable so it can be any name. I would just need the 
name it will have in TL2009 so that the package works directly... 
plain.mem, luatex.mem, etc. are fine for me... And also: how will it be 
found by kpse? With the --engine=metapost switch or a --engine=luatex?

Thank you in advance,
