If you manage to fully sync the wallet you can of course send all your coins anywhere you like, including a paper wallet.

If the the wallet is too large for synching on your mobile device, you can recover your coins on a Desktop computer using these instructions:

We do have an alpha version that synchs about 2x as fast. There is more in store for the coming weeks, but this is a good start. If you're interested in testing the alpha, can you mail us?
