Via current calculator http://www.pcbstandards.com/SiteIndex2.php This calculator is based on the heat rise of PCB traces. The via will actually run cooler due to heat sinking to the traces/plane on either end of the via. Anyway, it is a start and measuring the temp of a via during steady-state or transient conditions is doable.
