This thread seems to have gone a little quiet.  Are people interested in this service?  I've spent some time over the last few days working on an Android client.  Currently my app shows a page for generating a wallet from passphrase, salt and pin.  Once that's set up the app simply prompts the user for a pin.  When successfully connected the current balance and addresses are displayed.

I've wasted a bit of time last night and today with issues with the testnet but now I've managed to get some test bitcoins I want to work on sending bitcoins.  I really like the idea of BCC API but am a little concerned there isn't much interest.
