raidcoin.com - who knows something about "raid paper wallets"?

[dego]

A redditor today launched a discussion about the site raidcoin.com (domain owned by Mark Karpeles' Tibanne company). It seems to be a site which generates paper wallets in a way that a single private key can only be reconstructed if you have 2 of 3 paper wallets (or any other number you choose).

The redditors then speculate about if MtGox used these "raid" paper wallets for their cold storage (magicaltux talked about raid wallets) and might have problems to reconstruct the private keys. The algorithm is also investigated by the redditors.

I find that pretty interesting. Does anyone here know anything about that raidcoin.com site or raid paper wallets? Who "invented" the raid wallets? Who coded that site (I doubt it was Karpeles)? Has MrTiggr something to do with raidcoin.com? He mentioned it in #bitcoin-otc in 2012 here and there and was loosely linked to Tibanne through bitcoinpolice.org, another domain owned by Karpeles.

ATTN: Do not use wallets from raidcoin.com to store bitcoins. The PDFs for the paper wallets are generated server side.

Armory can do this in a much better way. It allows you to create m-of-n paper wallet with virtually any m and n

I am not promoting raidcoin here nor looking to discuss the pros and cons of it. I am just curious who implemented that site owned by Karpeles or about any other info on who introduced/invented the raidcoin technology...
