Isoft auction?

Further to my many earlier posts on Isoft, I note that the current tussle is quite likely to be resolved by an auction. According to the FT today, Isoft is discussing this option with the Takeover Panel.
"Uncharted water" indeed! Isoft shares are currently up to 71p - higher than the 69p cash offer from IBA. Certainly I would never have anticipated this and the "manna from heaven" gets better by the day for Isoft's shareholders.
