I haven't spoken to Limetech at all. Do you know if they have any threads talking about their plan for plugins?
I used python 2.6 since all the apps i've worked on work best with that so far. It's pretty easy to change, but then there would ned to be some testing done, and I believe ... couchpotato? breaks on 2.7. Is it just deluge that is using 2.7 right now and does that not work with 2.6?
All mine seem to be running 2.7.5 without problem.
These include (unRaid6.05)
maraschino - Yours
sabnzbd - unplugged x64 hybrid from the forum
couchpotato - unplugged x64 hybrid from the forum
sickbeard - unplugged x64 hybrid from the forum
headphones - unplugged x64 hybrid from the forum
Hope that helps.
