I've never liked travelnet. It's way overpowered and the recipe is way too easy for the utility it provides. Despite this, it is widely used on 'survival' servers. It really only belongs on creative mode or 'survival-lite' type servers i.e. where while resources are technically limited, they become abundant very quickly. This mod fork is associated strongly with the Pandorabox server, which falls into the survival-lite category because of the amount of public teleports and the ease of setting up a teleporting quarry ship and mining dense ore veins on the moon. If that kind of context doesn't appeal to you then I don't believe this mod falls in line with your true survival philosophy either.
The texture is awful, even in a variety of colours. You may have nostalgia for it, but I don't. A 'fancy' option is requested against the source repository and stuck due to merge conflict. This is an admission that the texture needs work, but also a kowtow to the old textures by not replacing them.
This fork prevents an old bug where you can fall if there's nothing below the travelnet.
The setup of a public travelnet is easy - there's still some confusion though. The setup formspec will tell you 'don't change the network name if you don't know what it does', then never proceed to explain it to anyone. How do you set up a private one? It's done by prefixing the name of the station with a (P). This is not explained. I only know it because I asked other players. The README should have tell you. The README's incomplete and the only other doc is the API spec. Clearly the devs care more about other devs than end users.
This mod is ancient (2013) and we deserve better. For survival I would much rather recommend teleport potion, which is somewhat more expensive and is only one-way single-destination. For running a server, I would rather recommend warps or funnily enough, another mod used on Pandorabox, telemosaic.
