It all rather depends on what the application is. That is to say, how 
much you want to invest in the solution.

I general, a standard servo type application, like this one:

http://elm-chan.org/works/smc/report_e.html

could have an application-level interface that accepts step and 
direction signals to create the position profile. Your application would 
be responsible for generating pulse trains that create an appropriate 
profile, exactly like a stepper. Does that make any sense?
