" Metagaming is a broad term usually used to define any strategy, action or method used in a game which transcends a prescribed ruleset, uses external factors to affect the game, or goes beyond the supposed limits or environment set by the game. Another definition refers to the game universe outside of the game itself. "
It could be argued that using RP in such ways is an attempt to transcend the rule set, with the code base and the design decisions forming the rule set in this case. Meta Gaming is a very broad thing, which is why it is impossible to really say something has broken it unless we are going to establish a single authority to make rulings. What constitutes meta gaming is likely going to revolve hugely around personal opinion.
