Are you looking to include provisioning support in a future update ? MfE is usless to me until this is available. As an end user of corporate email I have zero influence on their secuirty policies and wouldnt expect them to change their exchange config just for me. I have been using blackberry and recently tested MfE on the iPhone, would have liked to see how it worked on the N900.

(I checked the WiKi and there's nothing on there about future support for this, can you add something to say what your plans are ?)
