Yeah, but deadbase's site is like mothballed. The show database was last updated in 2002 and it looks like the site's last changes were 2005. If all you want are set lists, there's always deadlist.com too.
I think what the OP and I are looking for is a modern iPad/iPhone app version of Deadbase/Taper's Compendium. Imagine an app that has each show, setlist, technical data, as well as one of those long format reviews the Taper's Compendiums are full of! Imagine it including up-to-date source info including all the cool Charlie Miller sources, and maybe even the links to etree.org, archive.org. Add some video, some pictures and you've got something I'd pay $4.99 for
