I voted "yes" after looking over the conversation. Ironically that actually caused me to reject Edo Tensei.
My reasons may be unreasonable to some, but here I go. The zombies cannot be killed, near limitless chakra if not limitless, revived in their prime (this is not a gartunee since that old Suna lady was revived as an old lady), and in the case of dead Kage being used, they have the knowledge of their past life which, quite honestly, if someone very creative took advantage of, gives the summoner the perfect teacher for any non-bloodline technique.
On the flip side, I"m aware that they can be sealed away or defeated by soul stealing techniques, their personalities can be wiped, and most people will revive the zombies in their prime anyways. Bocc, imo, handled it very well during the Attack on Konoha, as all he needed was to use two zombies and himself to get the job done: Hide for offensive force, Himself to use susano'o, and Tau [who had his free will btw] to counter my companion's sound genjutsu (btw, whoever it was, Nathan I believe, who says sound genjutsu doesn't travel at the speed of sound, it actually does).
Perhaps I'm getting ahead of myself though, as I have seen some summons and people that could almost pass for a few of the above traits. All I would really need is one zombie to do combo attacks with and I'd be golden (only one I would get for that and he aint becoming a zombie anytime soon). My last worry is that someone will indeed ask Bocc or Trev to make them a zombie so that they can go running around in the service of themselves or whatever faction, with Bocc being the only convenient noose to tie them up.
If Bocc chose six great people who would be willing to follow him and made them zombies, he wouldn't need anyone else to defend the village, thus, he wouldn't have need for the popularity to get a huge gathering under his wing as loyal subjects, becuase, seriously, who attacks a village with even two near immortal people guarding it? If you say Bocc, I'll have to point out that both Rares and Yumei were unavailable at the time for their own reasons.
Just my take on the whole matter. Maybe as a custom technique overhaul Nara I'm overestimating the scope that people will actually think to use this technique.
