SSRS in Office 365 SharePoint Online

One of my Client asked if they can use SSRS in their Office 365 SharePoint Online site. Well the answer is simply NO. It is not supported in any Office 365 plan . I was looking for a definate answer to this but the only written thing I could found was this from SharePoint Online Forum.

"Based on the information I have available, this is not currently a feature of SharePoint Online -- also keeping in mind that it appears that this add-in must be installed on the SharePoint servers themselves, not remotely, and is specific to a user's SQL infrastructure.  SharePoint Online is based on SharePoint 2010, but due to the hosted, multi-tenant environment in which SPO is deployed, there are feature limitations vis a vis SharePoint 2010."

The only alternative which I could find was Business Connectivity Services (BCS) in SharePoint Online
