Oh, I was just asking about

luatexbase.add_to_callback("process_input_buffer", blabla, "blabla" )

and


luatexbase.remove_from_callback("process_input_buffer", "blabla" )

LuaLaTeX users do that way and I want to be sure it won't interfere
with ConTeXt way of doing things so I can play with the suggestion
made by Luigi.

Regards,

Jairo :)
