Aw yeah, the Internet can be a bliss. Sometimes. Works great for me at least, trying to learn more drums. :)
EDIT: Fun fact - he's left handed and I'm right handed, so I can just mirror my screen during active sessions so it looks like he's right handed as well. ;D
Tech improved since then quite a lot, even now we've got fiber here in the middle of nowhere. But also we do take turns most of the time. Pick a song, play one part, the other plays the next one. We're also looping a lot of stuff. Like - 3, 2, 1 - Let's go! And while he's playing and I'm playing we watch each other on the screen. Helps shitloads for me regarding leg work on the drums.
