Well, you'd get the numbers (sizes) from the kernel, as a response. Of course, you could define the interface such that the query (after all, that's what it is) contains the full field name plus size information, and the kernel just says "EINVAL" if it doesn't like it, but then you lose some flexibility. Might not be a big deal, though.
Yeah, perhaps it's actually better to avoid being overly clever. How frequently are ps and friends hit by the removal of fields or size changes anyway ?
Oh, BTW, it would be more like /proc/hack/<query>, so you do all PIDs in one sweep.

Well, that's what programs are for :-)
