Time to bring back single-wicket cricket ?

As we get closer and closer to the days when players move around almost at will - or to wherever the next pay cheque is (no criticism this, just natural order), and on a day when, like many I hope, I'm now watching Tendulkar bat like a god for a team in blue against a team in darker blue (who cares which team is which when you get entertainment like this?), I wonder whether the time can be long off for the return of single-wicket cricket. It had a revival in a not very serious way as an end of season filler at Lord's in the late 60s and very good it was too!
