Synthesized Scent over IP

There has been a lot of talk about how soon physical interactions over IP would be possible and also a lot of research has been going on this subject, to provide Touch-to-Touch, Motion-to-Motion and similar interactions. Last year a project called touch (http://phy2phy.wikidot.com/touch) demonstrated a device which allows two users to touch each other's fingers over the Internet. However, when these products would be commercially available, is hard to say at this point. There have been a few commercial products launched that deliver aroma over your desktop. A company called TriSenx has created a device called Scent Dome which has cartridges of 20 scents and by cleverly mixing these; it releases fragrances that provide a unique experience to users. So, whenever a user goes to a Scent Enabled Website (SEC), the device will spray the fragrance into the air as specified in the content, thus bringing a tinge of reality to the otherwise virtual experience. Another company, called Telewest, is soon going to release ScentMail which will use the same device to let users send fragrant email.
