Generally speaking I agree its a pretty good dungeon, but I think it could do with some trimming of the fat. 100 might be a nice round number, but I remember long stretches were I was just bored of randomly generated floors I had already "solved" numerous times. Granted those long stretches without accessible healing can make things more tense.

What I think was done right with the Via Infinito was that even when your characters were level-capped and had pretty much the best equipment availiable (Iron Duke non-withstanding), you couldn't just derp your way through it. If you didn't think encounters through you were liable to die very quickly to Elder Drakes, Mega Tonberries, Chac, and of course the final bosses. Heck, I even got nuked to hell with Ultima because of an Oversouled Mushroom Cloud to give me a game over out of nowhere.
