Thank you for reaching out to us.
The licensing for our Developer Tools products is developer-based, so each person working with our controls in development-time (e.g. Visual Studio) will need their own license. Once a developer is assigned to a license, that person can download the controls from our website at any time and utilize on any number of machines/servers/environments/builds/projects/applications/etc, there is no other licensing needed.
If the developers working on Webservices and business logic won't be working directly with our code, they won't need a license.
All the best,
the Telerik team
