Keith - I've been asked to separately review this.  Obviously we 
can't both agree to act as two separate reviewers.  It's 
probably/possibly SO&P-funded, which might be seen as a conflict, 
though I'm sure we'd be as rigorous as ever!  Though it sounds 
interesting, I'd say no due to lack to time (I've got a different 
manuscript to review at the moment).

Cheers

Tim
