Fotango to smother Zimki on Christmas Eve

Canon's subsidiary Fontango had created something really interesting in "Zimki", a platform for building scalable applications- a kind of David vs Goliath approach to the space Amazon EC2 is trying to pursue.
Whilst the management at Fotango were keen to opensource the platform, Canon felt differently, with the result that the project has been pulled. Anyone who can explain how this was a good outcome for Canon I'd love to know!
Gervase Markham points out that by Canon pulling the platform, ironically, they've helped prove one of the main reasons why the platform needed to be opensource to work. Simon Wardley, Fotango's now ex-COO must feel thoroughly justified.

Opensource Business-Model Guru?

I'm really interested in some of the hybrid business models being pursued in the US, where code is licensed under both something like the GPL, and also on a commercial licence in parallel for those that need it. It seems to me that there's a challenging line to draw between being too commercial to be accepted and to build a community, and between limiting your upside by going down the support model. However, in the UK Open-Source businesses do not (as far as I can find) succeed in raising Venture Capital, unlike the US (I'd be delighted to be shown how ignorant I am on that!) I've been trying, without luck so far, to track down someone in the UK who really understands these models as it's applicable to a number of our current and potential invstees- please let me know if you know anyone.
