My case is a bit more complicated as I also can't have non-secure (t)ftp! Are you saying that PXE can work without DHCP/BOOTP?

I think this could be made a general use-case. A meta-layer sounds sensible to get it going - this could then be added to OE-core later if that makes sense.

It would benefit from some scripting support in the image to personalise it as it boots (e.g. setting IP configuration, hostname, etc.) - I'm currently looking to do this by passing parameters back from the server through the kernel command line.
