I've never had to remove a search listing but have been asked to do so. I see there is a way to make a request in Google that lasts 90 days. Does anyone have any experience doing this? Can you get the listing back? How long does it take? Can it be done in Yahoo and Live?
I think the best way should be to write an exclusion for that page in your robots.txt and when you want your page back to the SERPs, you change your robots.txt again. The new inclusion speed will depend on the crawl rate for your site. If you have a Google webmaster account and use sitemaps, you should change and resubmit your sitemap too, this for shure will speed up the process. For later reinclusion, a few new deep links to that page will help too.
