I found this while surfing today: http://www.dopublicity.com/Digital-Signage-Software.aspx
It looks like this service offers some pretty decent content. However, it appears you have to use their software/hardware set up to access the content. I'm pretty new to the BrightSign world after switching from Scala Player/Designer after years.
Can someone with a better eye tell me if dopublicity could be a viable content provider for us?
