Aldiko allows you to read DRMd books as it allows you to enter your Adobe Digital Editions ID. If you add Calibre to your computer as well, you can transfer any library books you get wirelessly to the Vox. You can get Aldiko through a "direct download" from this site:

Select the "slow download" (download with waiting...about 3 min) and install.
There's another thread with more details about adding Calibre as a server (on your PC) etc.,
