The line you quoted does in fact work from Windows. I did not have
.emacs in that particular directory, causing some confusion. 

I have sent what appears to be a tramp specific problem in opening a remote
directory to tramp-devel. Other than that, single hop seems to work. 

However, I still cannot figure out multi hop. Using 
/multi:plink:me@my.host.org#3322:me@host.org:/home/me/realfile.txt
gets as far as 
Tramp:  Found remote shell prompt on `plink' 
and then hangs emacs hard-- the window does not redraw in Windows and I 
must kill the process from task manager. 

Adding 
(add-to-list 'tramp-default-proxies-alist
	     '("host\\.org#3322" nil "/plink:me@my.host.org#3322:"))

(with or without the port numbers) to _emacs causes 
/plink:me@host.org#3322:/home/me/realfile.txt
to get as far as 
Tramp: Opening connection for me@host.org#3322 using plink
before hanging emacs in a similar way (waited more than 6 minutes to 
be sure).
One difference is that in this crash, EMACS.EXE is taking 50% of cpu
time, whereas in the previous it was idle and taking about 2K more
memory. 

As my network is configured at the moment, the only service available is
ssh. I can exchange keys between my.host.org and host.org, but not from
the lab XP machines to anywhere else.

I have the following in _emacs, and the startup sequence echoes the load
command, so it is being read:

(add-to-list 'load-path "C:/tramp/lisp")
(load "C:/tramp/lisp/tramp.el")
(setq tramp-default-method "plink")

(nconc (cadr (assq 'tramp-login-args (assoc "plink" tramp-methods)))
       '(("bash" "-i")))
       (setcdr (assq 'tramp-remote-sh (assoc "plink" tramp-methods))
       	'("bash -i"))

	(setq tramp-debug-buffer t)
	(setq tramp-verbose 10)
tram-bug reports this:
Emacs  : GNU Emacs 22.1.1 (i386-mingw-nt5.1.2600)
 of 2007-06-02 on RELEASE
 Package: tramp (2.0.55)
 but the files in C:/tramp are 2.1.9

On Gentoo, using a suitably modified equivalent .emacs file, I first get
an error that trampver could not be loaded. In fact, this was not
created until I ran ./configure. Then I got the error 
Symbol's value as variable is void: tramp-gw-tunnel-method
this is true on OSX emacs 22.0.52.1 as well as Gentoo x86 Emacs 21.4.1.
make fails on OSX. On another Gentoo machine with Emacs 22.1 and
tramp-2.1.9-r1 installed through the package manager, I have many 
many more apparently unrelated problems. 

I also tried this with a cross port of tramp to Windows using mingw32 
and my x86 Gentoo machine, but still failed in the same way.
