Microstrategy as a front end to SAP BW

[sapen]

Our customer would like to use Microstrategy 9 as a front end to BW rather than Business Objects (in addition, assuming that the new products will be available by when we go live next year).
I have struggled to find any comments in forums (eg SDN) where people have discussed their implementation issues.
Does anybody have any experience with these two product sets working together?
