Has anyone heard of the IHSS program? If so, how does it work?

In Home Supportive Services is apparently a type of Medicaid service. I haven't heard of it in my state (perhaps it is called something else here) but it seems to be operating in California and Colorado under that name. There is information about it here, including the name of a person to contact for more information: http://www.colorado.gov/cs/Satellite/HCPF/HCPF/1212398222653
