Does KanBo need to be installed on its own separate App/Web server or can it be installed on our existing server as another website within IIS?

Does KanBo need to be installed on its own separate App/Web server or can it be installed on our existing SharePoint server as another website within IIS? We are a small organization (30 employees) and currently our SharePoint environment is just two-tier (App/Web on one server and SQL on another).

For 30 users is enough to create another IIS website on SharePoint server.
