Of course, texio.sprint("\write2{titi}") is forbiden, as the idea would be to eventually overwrite \write...tex.sprint("\write2{titi}") is ok and of course you can use io.open and friends
The idea was precisely to do it without the write macro... and the idea is to write in the aux file, this means something that will be opened with TeX (I can't do anything about it).
I hope there is a solution... -- Elie
