Using off-the-shelf technology, would it be possible to create a community-built array-style radio telescope? Much like the Very Large Array or Square Kilometer Array but using home grown antennae and the Internet to connect them.
If enough people got involved in such a project, could the resolution of such a telescope rival that of the above mentioned telescopes? The area of such a telescope could potentially be measured on a continental scale. Has anyone attempted such a project? Is it even feasible?
