The suggestion that one day we might have "virtual church services" is missing a big piece of the overall worship experience. Like televised services, an important element of "worship" cannot be duplicated through a medium. For someone to truly take part in a worship service, they need to be physically present and participating.
This is not to say that televised and "virtual services" do not have their place. For example: In the case of someone who physically cannot not attend a service because either they are to ill or they are a caregiver for someone who is, a virtual service would certainly help, but it would not be a substitute.
Technology will never be able to replace the experience of congregational participation. You just can't lump worship services in with online banking or a chat room. I feel safe in saying that no matter what your religion, worship isn't meant to be a convenience.
