I hold no hope for the Bing/Yahoo! alliance. On my money site Bing rarely crawls the top 3 pages that are updated 3x a week.
Bot comes, takes / and robots.txt and leaves. Later comes back for a long gone page about New Years Eve 2007. That's the full cycle. Once every so often (~45-90 days) it comes to crawl a page created and gone in 2009.
The Bing bot needs some serious energy enhancements!
