binary packages

I have a 486 with a small hard drive (under 1 GB) and 32 MB ram.  

I can successfully install and set up NetBSD but I would like to add a
few binary packages to the install.  I'm on dialup (2 KB/s).

Do I have to install the whole pkgsrc tarball to do it?

I ran out of time last night to see if the base ftp client can resume an
interrupted download.

Does pkg_add have any facility to permit interrupted installs of binary
packages?  My phone line is unreliable and may also be needed for normal
phone use.

Is there a way to get pkg_add to give a preview of how much disk space
will be used by a package and all upon which it depends;

	and how big the download is;

	and perhaps the list of files it needs to get in case it would
	be easier to download the tarballs on another box and transfer
	them via scp?


The packages I'm interested in are:

mc (midnight commander)
lynx
python
vim with python syntax

I don't need X on this box.

Thanks,

Doug.
