We use udpcast + partimage + DRBL to make multicast clone work. If you are interested, have a look at
The clonezilla has been used in our computer classroom here for more than 2 years. It makes us clone an 3 GBytes image to 40 clients in less than 10 minutes.

I too have had a lot of success with a homebrew project that uses partimage and udpcast. We image 100's of PC, when my employer buys in a new batch of machines.
We found that we would spend 20-30 mins setting up a batch of clients, before we start the multicast session, so we ended up breaking in down into segments.
By the I mean: The partimage file that is multicast to each image is broken up into blocks of say 60 MB each, and sent out to each client with a simple header that basically says `block 1 of 12`. The idea is that you can unpack a client PC and it can join the session half way through. The master PC just cycles through the blocks over and over again.
For example: the first client will get blocks 1 to 12, the second PC will get blocks 2-12, then 1, the 20th PC gets blocks 8-12, then 1-7. Once a client has received all the blocks it reassembles into the one file, and partimages itself, then reboots.
We end up with a conveyer belt effect: We unpack a PC and set in up at one end of a long table, then unpack the next, and the next, etc. By the time we get to the end of the table, the first PC has got all the blocks, partimaged itself, and rebooted into XP. So it is replace with another PC out of the box.
