I think the teleport/wormhole model may come in handy here and there.
But, to me, it really runs counter to any spatial model. Aren't
"teleports" analogous to the existing web links, where all links look
the same but actually 'travel' arbitrarily long 'distances'? I think
the current "everything's a teleport" situation in the web is one of
the biggest reasons that people have trouble navigating it.
