If available use rsync on linux, if you are on windows use wsl (ubuntu), or you can use this peer to peer website for sharing data :- https://toffeeshare.com/
If all of these options fail, quit bioinformatics, buy a RV and travel the country. I have considered it before.
Toffee Share seems to be rather promising. Only sky is the limit with this one and it's not for local use only like snapdrop suggested in the comments seems to be. This toffee share works almost exactly like what I had in mind. It's only for browser though but it works!
