Can two Apogee's be used at the same time? If I start with a ONE now, can I add a Duet later?

In theory yes you can by "Aggregating the Devices" in Audio MIDI Set up, which is an Application found in the Utilities Folder

Applications > Utilities > Audio MIDI Set Up

To set up an Aggregate Device: (Snow Leopard)
Go to "Audio MIDI Set Up"
Click on the + button on the bottom left of the window
Check ONE and Duet

Now, when you're setting your Audio Device (Audio Input / Output)
in your Mac, GarageBand, Logic, or MainStage,
Aggregate Device will be an option.
It basically combines the Inputs and Outputs of the devices you aggregate.
