I studied togakure ninjitsu, which Dr Masaaki Hatsumi is the 34th Grandmaster of, and i've been taught by some seniors who studied under him and Shidoshi Brian Hayes. There is a lot of public facing b*llsh!t involved in ninjitsu, but a lot is extremely brutal and effective. You can't show that on t.v. or in a dojo otherwise you'd have no students left, as they'd all be broken.
Even ninjitsu maintains links with koryu and tradition. But it is an art that evolves with the times, hence the gun-work etc.

Not really! Tanto of varying lengths were far more often used in seppuku. Waks were not intentionally used for that purpose. They were used, but it wasn't a reason for their existence.

Nope! Samurai were the only ones 'allowed' to carry 2 swords, not just a katana.

to buildings where katanas were not allowed, the samurai would carry a wakizashi anyway.
The wak is/was a house sword, the katana is/was a battlefield sword. Try swinging one of those around in a low roofed japanese house! It wasn't any kind of law about leaving katana at the door, it was probably common sense and as said, out of respect to the house owner. And it wouldn't be kept under his pillow. It would be standing up with the kissaki pointing to the roof, so the tsuka (handle) was to the floor and hence nearest to the samurai so he could arm himself quickly.
