According to the Guardian, the new e-conveyancing system is going to look as sci-fi as it sounds:

Under e-conveyancing, every chain will have its own progress chart, posted on a website. Squares coloured red or green will show when each party has passed each critical step of the property-buying process. When the whole grid turns green - and every party has given the final go-ahead - the transactions go through.

Actually, the Guardian's description - the best of today's bunch - is of a much improved system, that will take a lot of the insanity out of the final stages of buying or selling a house. All we need now is something can disarm the gazunderer or gazumper... after all, it'll take more than a network to stop some people behaving like shits in the days leading to exchange.
