I've not got much knowledge of network engineering salauolayemi,. I have been readin some interesting things recently though.
People are looking at changing data communication in office and factories. They are looking at using IP to transmit all data types (control included) to allow for a centralised network, reduced cabelling etc. Perhaps you could devise a piece of hardware (for home control) that could plug into a centrallised network. This way it could be controlled over the internet, a local PC or even a PDA wirelessly through a router?
