Pxe booting possibility so far?

A while ago i think i read somebody asking about diskless possibility..

So has it been implemented?

I'm using diskless program called ccboot and it would be great if unraid can read vm images from my diskless server..

Ccboot server consists if 4 disks, (except the server OS)

client reads image from image disk,

Second disk is what they called "gamedisk" which is essentially D disk or the disk for user upgradable content.

Client activity is then stored into another disk called writeback disk, and lastly theres also cache disk for caching

I was wondering would it work right away if install ccboot client on unraid vm?

Thanks
