Personally I think this is a big waste of DMT. Yes you bypass gut MAO but it still has to go through hepatic first pass (as that's where all the blood vessels go from that area) - and your liver contains lots of MAO enzymes which will happily munch up your DMT (much to our disgust) - and then it goes to the brain where there's even more MAO which again will happily munch it up. The only reason DMT works at all, ever, is by saturating the MAO enzymes that it will encounter with a large enough amount of DMT that there's some left over to actually bind to your receptors (or deactivating the MAO in question with a MAOI).
This is why smoking and IV DMT are the best routes, because the DMT is exposed to the least amount of MAO enzymes, they go pretty much straight to to the brain. You also get the whole dose delivered right the hell now, so you do the best job of saturating MAO you can.
Or you can eat a MAOI to get past all this, but this is another topic altogether and one many of you will be somewhat familliar with anyway so I need not go over it.
edit: I just had a rather amusing visual analogy, which was that delivering a dose of DMT is much like running through a burning building with a wet towel draped over you. You sacrifice the towel to prevent getting burnt. The bigger and wetter the towel is, the less you get burnt (bigger dose). By choosing the shortest route through the building (different routes of admin.) you avoid being burnt too. The amusing part was that the front door was an asshole, the flames were made up of little pacman-like MAO creatures, and reaching the goal prompted rainbow psychedelia but I disgress... hehe.
