you can run

	verbose9pserve=2 vacfs ...

and you will get a lot of debugging messages on standard error.
among other things, you'll get a trace of all the 9p traffic,
and you can check whether this is true.  i doubt very much
that vacfs is dropping messages, since it is a single-threaded
server with a simple

	for(;;){
		read request
		response = handle(request);
		write response
	}

loop.

network addresses and files are different kinds of names.
mixing them would introduce ambiguities, like what
if i have a file name 'tcp!bell-labs.com!http'.
also there was no obvious error response if you
dial "a!b!c!d!e".  is it a malformed address?
not if a file name a!b!c!d!e exists.  but in general, yes.
