I haven't seen anything about it on the portal Jake.
I played around with having OpenVPN installed on the router until late into the night and I'm not convinced it is efficient in the long run. While everything works (Netflix, Hulu+, VoIP, Home Alarm Monitoring, etc...) my 25 Mbps / 10 Mbps connection seems kind of sluggish. I looked at the bandwidth stats on the router and we are only ever getting a little over 1/4 of the speeds we see without it.
I'm going to try to find a balance between having everything use it and having just some devices / activities use it. Do I really care if the Apple TV isn't using OpenVPN? Or my IP Phones or ATA device? My wife really loved it because some shopping site which is currently blocked to my ISP (Anthropologie) was no longer blocked since we now appeared to be from Ontario or the US.
I must say though that having OpenVPN on my iPhone has made a huge difference when on public wifi. For some reason everything seems faster / smoother from there.
