Re: [Ice] Updated charter

["Ben Campbell" <[e-mail]>]

For the record, this version addresses my previous comments. IMO it 
looks good to go, modulo the separate discussion about the scope of the 
work. (much of which could be adopted post-chartering under the "new 
work items that follow this pattern" clause.)

Thanks!

Ben.
