There presently is a sort of solution. It requires you to build all your wonders near your /home location then making your /home publicly accessible (see Bukkit Commands for players
). This sort of goes against the no-warps convention for Survival but it limits everyone to one "warp" they can set. And in case you haven't noticed, I think compasses now point towards your home (if set), not spawn.
Having said that, I have been tempted to remove player access to the public/private/invite aspect of the /home mod. Part of Survival is that things aren't easy. If you want people to have easy access to your creation, make it in the Creative server. I much prefer chancing upon/discovering the creations on the Survival server. That is part of the thrill of exploring.
As for waypoints, yes there are ways to do it already, but again, the question is whether this goes against the type of Survival we want.
Remember that there is always the Creative server, and screenshots can be placed on the forum to dazzle us with the brillance of your creations.
ps. Roads and tunnels are never a complete solution. Not everyone likes them near their work.
