Hmmm, very cool.  The standalone program was just what I though of first; 
I'm just used to tcopy from old HP-BSD tapes :-)

Also, the standalone program works from booting fron any possible media; 
tape, network, presumably disk (though, what's the point? :-)  I figured; 
I need a way to boot the miniroot anyhow, so why not use a boot-like 
program to install the miniroot?

Right, mne doesn't require storing the images locally.  In fact, to test 
it, I connected to ftp.NetBSD.ORG and installed 
{etc,dev,bin,sbin,var}.tar.gz from the last hp300 snapshot.  It was a 
little slow, but you can just let it run overnight.

They way I do FTP is emits an `' which:
	* cd's to the target directory
	* starts ftp
	* feeds ftp the proper commands

The program prompts for things like server IP, server path, 
login, password, and files.  It stores these responses as default answers 
in the event that you goof in the password or something, so you don't have 
to type it _all_ over again...
