Yes, it is. To save the image, just run the udpcast receiver on your
fileserver machine, from the command line:

 udp-receiver -f image-file.bin

To restore it, start a sender:

 udp-sender -f image-file.bin

Note: if your fileserver machine has more than one interface, you need
to specify the interface that you are using:

 udp-receiver -f image-file.bin -i eth0
 udp-sender -f image-file.bin -i eth0

Compression/decompression happens on the machines to be imaged.
