If not, why not? If so, how? Sure, why not? Assuming no errors (otherwise the question is really stupid), the only overhead is acks from the receiver (`block 0 OK', `block 1 OK', ...) Assuming the protocol has a reasonable window and the acks are smaller than the data, this doesn't slow anything down. Of course most protocols delimit the blocks. --Joe
