You're welcome
If you really plan to use the redirect to mask blackhat link building then it's really just a guess as to how effective it'll be. There's definately things ways to use redirects that way, but usually they'll just be good for short term gains. Really the only thing I can tell you about that is give it a try and see how it works. I'd be careful though doing anything too fishy on a site that really matters to you.
I think for what it sounds like your planning to do it would be better to make some link silos and then do all the link building to those. If you do anything that hits one of the silos too hard then just abandon any of the backlinks from it to your money site and then continue on with the rest. Then just continue with a small amount of whitehat link building to the affected silo until it seems to come back to life so to speak and then you can use it again. Or just abandon it completely if you want.
It just seems to me you'd be better off working a strategy like that, but then I don't know the exact details of how your planning to do the redirect strategy either. lol.
edit - I know that would be more like the web2.0 example you gave, but like I said I think it would have a better effect than trying to get all the linkjuice transfered through a redirect.
