Powerpoint used for learning profiles

I met a chap the other day who's been developing subject-specific e-learning profile templates in PowerPoint. Developed to fit the Every Child Matters agenda, they aim to assist transition between Key Stages 2 and 3.

Essentially these templates act as a portfolio of the student's work, hyperlinking to examples and other relevant documents. He said he used PowerPoint because it's free for teachers as every school already has it - a point which I would challenge, but the templates could easily be replicated in other presentation software - and that it is familiar and flexible.

I have some questions about using proprietary software and changing the nature of a tool (is it a presentation tool or a work management tool?), but my bigger question is about how this fits in with the government's drive for e-learning platforms and e-portfolios:

"The government’s target is that all pupils will be able to access a personalised online workspace, capable of supporting an e-portfolio, by 2007-08" (Learning platforms, Secondary: Making IT personal, 2005, Department for Education and Skills, London).

Is this PowerPoint project a good example of an e-portfolio that can sit on the learning platform, or is it likely that the learning platforms will be developed with a specific mechanism for developing universally acceptable e-portfolios? And are there/will there be specific guidelines - distinct from Every Child Matters - on how an e-portfolio should be put together?
