Sure do!
Only concerns with E85 are that BMW state that E10 is the maximum ethanol you should run. Given the fragile nature of the HPFP, I'm not so sure it is a good idea to aggravate it with 85% ethanol given the corrosive nature of the stuff (however a very reliable source tells me that any car that is engineered to run E10 will also be fine running E85 - from a fuel corrosion point of view).
The second thing to consider is that E85 requires a significantly richer mixture to achieve stoichiometric, so at elevated boost levels you may run out of injector capacity (to inject enough of the stuff to achieve the mixture you are after).
I think I'll wait and watch to see how others get on with E85 and the HPFP.
