I have a question. If I format the string, will it be sent as a string? Can I send packages as raw bytes to increase bandwidth?

I'm not sure if I may bump this topic, but I need help. I try to remove mpg123.dll from the game's folder and the EXE file just won't work. Also, I'd like a totally GPL-/LGPL-less game engine because I really don't like that license as it could terminate rights of players who would reverse-engineer ...
