Hi All
From what I understand, espresso's offering of a linux server is based on the NetPilot Remote appliance.
The unit only has espresso installed and has no other functionality that the CachePilot runs. e.g. Content Delivery, Pre-caching, Integration with all content providers (Channel 4, Espresso, Pearson).
The CachePilot has all of the above funcitionality, as well as VPN, Firewall, Full Integration with Stanns Guardian and Secure Computing.
The standard cost of a CachePilot is also £1125.
I work for a distributor of Equiinet and we are accredited CachePilot Distributors.
Should you have any further questions, by all means please ask.
Thanks
Sheps
