I agree with you on it being backwards and for some reason I chose to do it this way, though I can not now remember why.. may have just been a flawed though, as I can see no reason not to do it your way at the moment.

Good find on the fread, that is actually a "bug", should be MAXBUFLEN instead of 100.

Agreed on multicast, I will add that to do the todo.

Thanks for your feedback!
