I'm not aware of any alternatives to oauth-plugin at the moment, though it is definitely getting long in the tooth and ripe for a replacement. My recommendation is to generate the oauth server from oauth-plugin, then extract the dependencies from the plugin (which are just a couple modules worth of methods) and trash the plugin. Then tweak everything to your needs. 2-legged oauth should not be a big problem since it is simpler than 3-legged anyway, and my feeling is that oauth-plugin is not usable these days without significant modifications anyway.

The meat of OAuth has long been extracted into the base oauth gem anyway, so the oauth-plugin is sort of in limbo. The architecture makes some heavy-handed assumptions about what authentication system you are using, and the generated code is dated. So to me, oauth-plugin serves more as an example of how to wire everything up rather than something that most sites would want to use out of the box.
