I should have mentioned this in my previous email, thanks Job for pointing it out.
Another key difference between DBLRA and incrementally updated backup strategy is that with DBLRA you can restore to any point in time. For each incremental DBLRA receives it creates a virtual full, so the user has the choice to restore to any of these virtual full backups. Whereas in an incrementally updated strategy the updated copy cannot be undone, hence it's not possible for the user to restore to a point prior to the one represented by the updated copy.

Its different in the sense that the DB server doesn't has to get involved in applying the incrementals. The Appliance does it for you, say you take a rman level 1 backup, and then when you do an "rman list" you'll see a full backup not an incremental.
In addition it also validates the backup, so you don't have to run "rman validate" on the db server anymore.

Is this different from the incrementally updating backups feature of rman or just a more automated version of it?

Other than the first full backup, with this appliance the user will never have to take a full backup again but will enjoy the benefits of a full backup. In this setting RMAN will never read or send a duplicate block to the appliance hence the impact to the DB server will be minimum, highly proportional to the amount of change bits.
