I've heard of "SETI@home". Is there a similar program with Spacewatch®?

There used to be.  In 2003, Spacewatch® started the "FMO Project" courtesy of funding from the Paul G. Allen Charitable Foundation. This effort ended successfully and fruitfully in Spring of 2006. To read about the project and to see the results, you may access our FMO Project webpage through FMO Project.
