New telescope technology

When do you think we'll see active optics filter down to amateurs? It
seems to be the most exciting thing happening in astronomy at the
moment.

On the subject a completely different technology, have there been any
initiatives to set up amateur telescope arrays? The proliferation of
broadband, telescope computer interfaces and incredibly powerful CPU's
for image processing could lead to some exciting results, I would
imagine. Do you think this would be feasible?
