ColdFusion MX 7 ships with a new version of Verity K2 Enterprise server which is (now) used for all ColdFusion Verity processing. Verity K2 is a server itself, and ColdFusion is a client application which connects to K2 so as to perform searching, indexing, etc.
The ColdFusion Administrator’s Verity K2 Server screen allows you to specify the name of the host running the K2 server to be used as well as optional ports and alias names. The seems to imply that ColdFusion can connect to a remote K2 server, perhaps to allow multiple boxes running ColdFusion to all share the same single remote K2 server.
Unfortunately, this is prohibited under the license granted by Verity. Multiple instances of ColdFusion running on a single server can indeed all connect to and use a single local K2 server, one Verity K2 server responding to requests from multiple ColdFusion servers (instances) on the same server. However, in order to access Verity K2 on a different box you will need to purchase a Verity license directly from Verity.
