- | The other thing to consider is that if Vara figured out a way to increase the speed in a closed-proprietary way, it's just a matter of time before the Open Source Ardop team catches up. Personally, I tend to favour open source options to closed proprietary ones not only because it's cheaper for myself, but also because it lowers the entry bar for others in the community to join. If HF P2P is really important for our community, then we probably don't want to exclude people who can't afford the $100 entrance fee, so I vote: **Ardop**. | + | The other thing to consider is that if Vara figured out a way to increase the speed in a closed-proprietary way, it's just a matter of time before the Open Source Ardop team catches up.
