Schools Interoperability Framework and UK/Linux

Does anyone know what affect the Schools Interoperability Framework is going to have on UK Schools (if any) ? If there really is a push towards common data formats (XML) for tools within education, then this can only be good for open source solutions (I would say). Anyone looking into this? http://www.siia.net/sif/default.htm (Thought I would mention it - I don't recall there being any comments about this in the past ... but could be wrong). Kevin.
