as recently as in IC the dcu was shown to be a multiverse -- there were a number of variations on superman himself. in many different threads scans HAVE been shown to say it is a multiverse (juntai showed some great spectre scans, to name just one). just recently captain atom DID travel to wildstorm (atom respect thread has scans if you're looking for proof) and there have been many xovers with dcu and vertigo to show they are linked as well (jla/sandman to name just one i could dig up were i not so lazy.) we have waverider guarding hypertime, we have kismet overlooking it to keep it from unravelling . . .
not sure what MORE proof anyone could need that the dcu is multiversal both with AND without factoring in hypertime.
and it also seems ridiculous to me to say one continuity is larger than the other. god=god, both are the ultimate expression of infinite, and all other infinities by definition<god.
once agin -- IF geb=god, geb is INFINITELY>hotu+lt+ . . .
but since no one seems to know for sure, the discussion is really pretty silly -- especially when everyone keeps expressing opinions as fact.
