Nah, he was speaking in very general terms about some way to send money, quickly, easily and anonymously to content creators. That's not far off from what he's been evangelizing for decades, so I see no significance in his mentioning it at any particular time in 2009.
Has RMS made any public comments about Bitcoin? In light of his past commentaries, he should have something notable to say about Bitcoin. If his public mentions of such cryptocurrency ideas cease after Bitcoin's metoric rise around October 2010, about the same time that Satoshi disappeared, this might be a significant link.
