(No clue on the rest, but I can handle this:)

You can use vnd devices (See vnd(4), vnconfig(8)) to swap to files.
Make sure lines like the following are in your kernel config:

config		netbsd	root on sd0 swap on sd0 and vnd0
pseudo-device	vnd	4

Then something like this should work:

dd if=/dev/zero of=$SWAPFILE bs=1k count=$SWAPSIZE
vnconfig -c /dev/vnd0b $SWAPFILE
swapon /dev/vnd0b

I don't use NFS, but you may want to read diskless(8).
