Do we have any idea (best wild-ass guess) when bitID may be available in the mainline Android client, something even marginally better than "between yesterday and in two forevers"?
In the case of Mycelium, we have a working demo in our dev build, but we are going to hold off until we get HD wallets finished. Reason is that without, your BitID will only be tied to a single address, and with HD you will be able to have a different ID for different sites, all coming from the same seed used for your bitcoin addresses.
