It would be nice for this to allow you to transmit power between the two places, making a orbital platform that is 100% dependant on the planet below and the planet below dependant on the platform. I know there is an orbital power transfer mod but adding that as a feature to this mod would make sense...
Additionaly, why the hell do you need bioflux for the space elevator construction? Replace it with carbon fiber and you have an alternative that makes sense cause right now you're using materials that spoil into the fabric of your elevator!
Right now the balance is interesting cause you would think this is better than placing a bunch of silos and using resources but I'd say that on most planets it's cheaper to get silos than get all the base planets... On vulcanus it's way easier to get silos, on fulgora you also get these things for pretty much free and on nauvis you got a lot of resources already for this... As much as I like this concept, I wish it would be more powerful or more useful...
Maybe it could work like space elevators from SE, where you can use trains to move things onto a platform from which you can then transfer them using one of the in-between platform moving mods, leading you to have a lot of throughput and the ability to make a space dock, or maybe you could have chests that link the platform inventory with the recepticle chest, then you could just use some circuit logic to transfer a lot more items.
