Mobile BI Licensing

If there is one topic I hate talking about it is licensing. It never seems to be easy and always confusing. I'm in a situation where I just can't seem to get a simple yes/no answer.

Is there a licensing cost to setup and use Mobile BI on an existing BusinessObjects Enterprise 4.0 installation?

I've been to the last two BusinessObjects ASUG User Conferences and have not got one indication that there was a cost. Yet I have a (new) SAP account rep saying differently. Note: The account Rep is our 5th one in six years.
