Great question. I’ll answer with more questions!!
What kind of technology and more precisely, what protocols would be required to access a future web server or web service?
Can such a server or service can be reached and/or interfaced from our location in time and space? That’s a pretty hard one.
I can’t find it right now and I can remember the name… But there’s a story of a computer, on which it’s owner received messages that seemed to come from the future. It’s been posted here not so long ago. It’s an amazing story.
