The apps would need to have a custom URL scheme registered in their info.plist. A registry site was launched a while back in an attempt to make it easier for developers to discover existing custom URL schemes: http://handleopenurl.com/ Unfortunately, the site has been blacklisted by Norton Safe Web, so click at your own risk.
UPDATE: The site is no longer available. Click on the original link only if you want to fall into the vast emptiness of the web or visit the Wayback Machine at Internet Archive to see the site in its glory days.
