Subject Re: [DISCUSS] Improving VR services such as password server
Date Fri, 20 Feb 2015 09:18:19 GMT
Do you know of any plans/possibilities to completely get rid of the VR and move functionality
- especially routing traffic - in host agents?

On another note, something more pluggable would be nice. One thing I'd really love to see
is OpenVPN support (because anything else is just a world of pain).
