I saw that Supercollider 3.11 beta 1 comes with Ableton Link support
I know Rui Nuno Capela is working on Jack Link, a Ableton Link
implementation for Jack (Transport).
Interesting developments to keep an eye on. Ableton Link might be
fitting well in the Linuxaudio environment with all those (small)
applications that support Jack (Transport).
