i wud definitely try the homeseer and insteon things at home because i am making my home into smart home. i had wired the ethernet wires to several rooms from basement. i have made a old used pc into media server with 3 hdds that has over 130 dvd movies so we can select the movies on media network to watch in kitchen or living rm or bedroom, but i am interested in home control things like rick's mention about doorbell ringing sent emails and, of course, light controls and HVAC controls.
PS: maybe i will have some questions for you, rick and grayson after i ll install these toys !
