I used to swap via 10/100 to a remote ramdisk via nbd on debian sarge 
(2.4 kernel)
and it  allowed me to work on larger images via Gimp. I have not done 
any benchmarking
though. Qualitative statement: It seemed faster than using the old IDE 
drive for swapping,
maybe because the image data came from the IDE drive as well and so the 
extra 10MB/s
channel via NBD was worth it.

I saw no stability issues.
