std::vector<char> (even with additional offset and length parameters)
introduces significant overhead for users that do not otherwise have any
reason to use std::vector.  I do not think the additional safety
provided is worth the cost of this overhead.

Requiring that the size be known at compile-time, and that an actual
static-sized array be used in order to call the receive function, is
definitely not a good idea.
