Even better, if you are printing the conducting layers on- you could coat the printed board with a layer of non-conducting lacquer/varnish and print another layer of 'track' over the top of that. As big a multilayer board as you wanted, and no vias needed, just gaps in the insulating layer where you want conducting layers to contact... it would be murderous to debug though!
