It is my understanding the it is the underlying GOX feed and NOT CM that is the problem. If that is indeed true then a premium offering would only offer the same level of service with more pissed people.
I could be wrong.
I am working on a solution to provide the real time data for my site from my server (with a back-end connection to Gox). This should reduce the Gox streaming load by ~600 clients (as of now), and it will make the site reliability my responsibility.
This will still be a free service, but with much better reliability (hopefully

).
However, I am also working hard on a premium offering (RTBTC) that will be much better than the free data site. As always, stay tuned!
