Different portal shapes are totally possible!
Even if that's from a different mod it still gets across the idea
We have put some thought, at least, into the idea of removing Stargate (It is an INCREDIBLY old plugin, last updated for Minecraft BETA 1.5) because it will likely become unusable going into 1.8 (No UUID support, no bug fixes, no support at all, in fact). We are looking into ways to replace the plugin, though we may well just remove it in favor of rail, road, or something else.
The only problem with a huge rail system is that someone needs to make it!
Maybe a good idea would be offering incentives for cities to connect themselves with the rail network, at their cost? Open to ideas!
