While USPS indicated that this wasn't a valid address, in the interest of not trusting software as much as real-world tests, I sent mail last week to that address.
(For what it's worth, it contained a single sheet of paper, upon which "Where Is Van Mantra?" had been written with a black magic marker.)
Today, as mostly suspected, it was returned to me stamped No Such Number.
So, it's definitely a fake address, unlike the one first used as Van Mantra's address when "he" owned the domain (and which served as the first link between EHWR and Mind Storm Labs).
