"see, i would seed them. i find seeds to be unpleastant. i'd halve & squeeze them, then pick the remainder from them after boiling them."
Luvs - I'm sorry but I think you're a little bit confused here.
First off, per the very link you provided for "Tomato Concasse" (which I'm aware of & do prepare once in awhile) the tomatoes are WHOLE when they're scored & DIPPED in boiling water for peeling. They're NOT halved & seeded before the dipping, which is what you said & what I was questioning. If you were to halve & seed the tomatoes before dipping them, the flesh would partially cook & absorb SO much liquid, the tomatoes would literally disintegrate. And the tomatoes are really just "dipped" in the boiling water for 30 seconds to a minute depending on the size & type of the tomato - not actually "boiled".
Also - the original poster was talking about tomatoes - FROZEN tomatoes that is, for sauce, & a concasse of tomato really isn't used for sauce, unless the sauce is really no more than a gourmet garnish or a fresh rustic-type sauce for an appetizer portion of pasta.
