Journal: UK supermarket Tesco will sell software from Formjet (who?)

UK supermarket Tesco will sell software from Formjet to try to compete with Micro$oft, so says BBC news - <URL: http://news.bbc.co.uk/2/low/business/5396488.stm>

Does anyone know anything about Formjet?

And I wonder, why don't Tesco do the sensible thing and sell open source?
