Are there any cases of security-like instruments being explicitly declared out of bounds for the SEC? I'm thinking specifically of bond-like assets or "evidence of indebtness" emitted by private persons on MMO rpg assets which have real-money trading options either as proposed by the game editor or in third party markets? Even more specifically I'm thinking of EVE online's PLEX items who area open to in game market and have been known to change hands within various ingame organisations for very real money. Some of these organisations have schemes to offer tokens of indebtness in exchange for the acquisition of these digital items that could be construed as a proper security if I read this right. Am I missing something?
