Many of the android phones such as the G1, Mytouch, Hero (and probalby Nexus 1) can support USB host mode if you root them and install a recompiled kernel. The original droid was rumored to have this capability in the shipping firmware. But that's only the start of the capability you need - a lot of devlepoment would still need to be done. And it's fairly painful development, in that once you switch the USB to host mode you loose the normal ADB development channel into the phone, and have to set up ADB over something else like wifi in order to load and debug your code.
So in effect, this is a project that can be done today with careful selection of the phone and selection of a developer with the right skills, and sufficient determination. But it's not going to be easy, and the requirement for a rooted and modified phone means it's going to be hard to market.
