Rackshack's prices with a privanet option?

[dRD]

Our traffic requirements are rather hilarious for most people, but we consume over 3TB external traffic a month and over 800GB of internal traffic (db queries) a month. Obviously this is relatively cheap as we run our servers at Rackshack -- 700GB of monthly traffic per box for ~$100/month is not bad.

But, almost similiar deals are available from other ISPs as well, so I was just wondering would there be any ISPs out there that can provide 100MBps connected boxes with ~400GB/month or more that could be relatively cheaply built so that they are interconnected to each other (read: normally two NICs or some other method) -- at RackShack we spend 800GB for internal traffic between our app. servers and db servers and RS charges same price for that as it does for external traffic.

Also, in many other ways would the "privanet" be rather good -- load-balancing, etc would be much easier to build using LVS and similiar solutions.

Ideas?
