vLite and slipstreaming SP1 on windows xp-machine?

[ZenLord]

IIRC you couldn't slipstream an XP-SP in an XP-iso on another OS than windows XP. Is this still the case with Vista? Do I really have to install Vista only to be able to run the slipstream utility in vLite or not?

BTW: I looked for installation requirements on vLite, but didn't find any. So if vLite is as good as nLite, then this would be my only gripe with it

/EDIT: and if I want to slipstream the 64-bit edition, do I need to do it on a 64-bit machine? That would probably raise even more problems, as I do not own any 64-bit hardware myself.
