In dynamics CRM, user can see activities related to a record by clicking left navigation and it shows all the activities (Phone, Task, email etc.). However there is no way user can see activities of related entities at one place. 
It can be achieved using Activity Summary grid

It is a Silverlight application, built on top of a base solution from CodePlex by marekhuk. The grid displays all the activities, it displays activity preview, attachments on selection. Activity and attachments can be opened from the grid.

It can be deployed on on-premise, online versions of CRM.
