For those who cant wait for the official release of Beta apps; feature to PAM that would also grab the updates of Beta apps.
As a developer said here:

This would mean easier updating for every regular user of portable applications and might also include a special Beta updater for beta apps. (This will increase the testing of apps in Beta). My choise would be to integrate it with the PortableApps menu while keeping it as a separate application. (Easier to maintain and update)
