I have developed a collaborative white board with Flex and LCDS.
The server runs on the computer of the meeting animator. Members of the meeting connect to the application with their computers.
There is just a SWF file on the server.
1. Is the Single-CPU license is valid for this type of application?
2. If several meetings take place in same time with each time a server on the computer of animator (without communications between these servers), can I use the Single-CPU license ?
You may be speaking about the LiveCycle Data Express edition. If your application only uses LCDS 2.6 then the express fits the requirements that you describe. You can use that edition.
Be careful with the new versions of LiveCycle Data Services. The version 3 is a beta version available on labs. There is no Express edition for this beta and Adobe didn't announce any LCDS 3 Express edition. You have to wait the public availability of LCDS 3 to see if the business model changes.
