script to auto answer video chat invite

My search has been unsuccessful for a script to use with iCAR to auto answer an invitation (or accept and invitation) for a video chat in IChat av. i would love to use this to “monitor” my home from work by “activating” the isight camera from my work computer. Thanks for your help.
