This is really interesting. I haven't tried the "-remsh" option on
Windows yet, but it looks like it's not registered that it's supposed to
connect to the running broker. For comparison, here's what I see on my
Linux machine:

~$ erl -sname foo -remsh rabbit at shortstop
Erlang (BEAM) emulator version 5.5.5 [source] [async-threads:0] [hipe]
[kernel-poll:false]

Eshell V5.5.5  (abort with ^G)
(rabbit at shortstop)1>


Notice how I said "-sname foo", and the *prompt* I'm given says
"rabbit at shortstop", indicating that I am issuing commands into a remote
erlang instance, not the local one. In the text you copied into your
email, above, we see "yhe at yhe" as the prompt, indicating that commands
you enter are being targetted at the *local* erlang instance, not the
remote one named in the "-remsh" command-line option.

I'll try to find a windows machine upon which to experiment.

If it's also the machine name, perhaps the following will do the trick?

erl -sname temp -remsh rabbit at yhe

The number-of-messages-seen could be added fairly easily. The number of
messages currently on the queue is already present. What do you mean by
"failure of delivery", in this case?
