I can barely imagine the code wizardy required to pull off something like that and get it to work. Trouble is it'd all be wasted effort unless smugglers could be convinced to forgo the established "good smugglers aren't seen" mentality and ride the lanes/gates. I think the coding would probably be the easiest part.
In the mean time I believe we can reach a reasonable balance by altering the smuggling routes between the buy and sell points, getting the smugglers seen would be the first step and cutting down the long flights between jumpholes would be an absolute god-send. What do you think Blodo, can the dev team get behind an idea like that?
