This does not make me happy, it makes me confused.
And it can't be right since A7 supports sending structs and other lite-c data structures. Look in the manual under "send_data_to".

EDIT: I do not think it is saying that lite-c doesn't do MP but rather if you only buy the Lite-C version of GS, you don't get MP. If you buy Comm or Pro, you do get MP, which Lite-C can do.
