Here are a couple of use cases: Windows: http://technet.microsoft.com/en-us/library/cc722358%28WS.10%29.aspx
Solaris: http://redhatcat.blogspot.com/2008/07/loading-pxegrub-from-pxelinux.html Other random proprietary software: http://syslinux.zytor.com/archives/2006-April/006811.html It seems like what this requires is to leave the UNDI & PXE drivers loaded, then load the chain image and jump to it. If this isn't supported as-is, no worries, just wanted to check if it was expected to work. Let me know if you need more information on Windows. I am not a Windows guy myself so can only go so deep.

It's not supported because of a priori no clear benefits present. @Seth can you comment on Solaris part? DOS is best loaded using grub+memdisk (later one is a helper available from syslinux pages).
