I'd like to be able to debug webworkers in their own environment (though I would accept the Chrome workaround of debugging in an iframe).

Possibly terribly inefficient but a hot cauldron of awesome! Beside the name "Mactronic" I think the customized activation unit that replaces the paper tape is amazing.

It appears that two browsers (Firefox and Chrome) on the same machine can edit a board, but it can't be edited by two or more machines at the same time. Bummer.
