Keep an eye on http://www.bbc.co.uk/radio4/schedule. Nick McGrath, Director of Platform Strategy, Microsoft Ltd recorded a programme with Alan Cox, Open Source Kernel Hacker (and one of OSSGs past guest speakers) on Monday 5th March 2007. Nick informs me this is likely to be broadcast on Radio 4 at 2100 hours on Wednesday 11th April 2007 (interestingly the date of the next OSSG event).

Looks like a good one and it looks like there is a good chance the recording can be downloaded after the broadcast
