Latency on a home fibre will be significantly lower than a 56k dial-up connection.

Somehow the artists could collaborate remotely using a shared MIDI clock. Admittedly it was techno which is both loopy and predictable, but still a cool achievement nonetheless.

I have home fiber. Again, I have 20 ms to Google. 40 ms (approximately what you'd expect from two not-physically-far-apart home fiber links) is already in the range that playing traditional instruments in sync is basically impossible. At a more typical 100 ms between nodes, that's a full 16th note of lag at common tempos. You can get up to 200+ ms between continents.

I know people that have also done it with techno, but they consider the lag as part of their unique sound. It's not something you can do with music in a general purpose sense.
