The title of the Financial Times essay is "How to Solve the Problem of the Dollar". It is written by Fred Bergsten formerly of US treasury. The plan is for the "sovereign wealth funds" to exchange their dollars for IMF SDR's which are backed by US treasuries and gold.
Basically, it's an attempt to prevent sovereign wealth funds from actually "spending" their dollars.
"The world economy faces an acute policy dilemma that, if mishandled, could bring on the mother of all monetary crises. Many dollar holders, including central banks and sovereign wealth funds as well as private investors, clearly want to diversify into other currencies. Since foreign dollar holdings total at least $20,000bn, even a modest realisation of these desires could produce a free fall of the US currency and huge disruptions to markets and the world economy. Fears of such an outcome have risen sharply in both official circles and the markets."
"There is only one solution to this dilemma that would satisfy all parties: creation of a substitution account at the International Monetary Fund through which unwanted dollars could be converted into special drawing rights, the international money created initially by the fund in 1969 and of which $34bn-worth now exists. Such an account was worked out in great detail in 1978-1980 during an earlier bout of currency diversification and free fall of the dollar that closely resembled today’s circumstances."

It reminds me of that saying about putting several spiders into one jar: eventually you have one big fat spider. I would rather see an unending fight for temporary advantage than see it settled permanently.
