it's not that it would be impossible by any means... if enough people got together and were serious about it, anything could happen...
i personally hope that happens; but i guess it only depends on people pooling their resources and really trying to learn the processes... it would be alot of work, but if a new "generation" of people had the skills and everything needed to make bridges successfully, that would really prolong BC's life even more
of course, you wouldnt want to start on something too complex dealing with complex animations and such lol
