I'm new to this problem (so please jump in and correct me if I'm wrong) but it occurred to me that Twitter could require that their most trusted "preferential" clients proxy requests from native apps through their own servers, which do the authentication. This would be a pain for these clients, but if Twitter really wanted to do this they could probably justify that it's the price you have to pay for preferential access. Edit: It just occurred to me that this might just be kicking the can down the road: you would end up with same problem authenticating with proxy server. It would have to be something along the lines where the proxy server itself has preferential access, but the clients to the proxy server do not (e.g. they are rate-limited by the proxy or something.)
