ok guys, I think I can answer these, but Pete's the authority.
My understanding of the current version is that I think it does all your asking.. i.e. you can re-rund tests, on demand from the package via a simple interface (you can select sub sections or whatever).
I also thought that it was possible to essentially *ignore* tests a-la production env. Although this change may not have worked its way in yet.
So basically I think Lars' points 2 & 3 are already covered. 1 maybe but I need peter confirm that.
Calling Mr. Harper! can you pitch in when you get chance?
