WetGeek I'm tempted to see if I can start a couple more instances of Transmission on that rather robust machine and seed even more.
After writing that post, I found rTorrent in our repository, and found out that I can run multiple copies of it in a terminal, and I can run multiple terminals, each in their own workspace. So I'm excited now. It uses ncurses for a UI, and it's written in C++, so it will be very light on resources. All I need to do is learn how to set it up and use it.
I realize there will be a learning curve involved, but I'm encouraged by that opportunity, and as I write this, I'm printing out a copy of the rTorrent manual. I'm really looking forward to getting that machine humming, cranking out copies of all four Solus editions. I'll keep using Transmission until I have rTorrent up and running.
