The good idea is to deliver Mobility Services as appliance as SSPR, Filr and iPrint is.
sure, think that would be true for my customers too. But I kind of gave up on the hope for an App after ZENworks Mobile Workspace was terminated; this had both the App (at least a good start) and the needed security... working together cross silo seems not to be MF's strongest point
Oh, actually I wish there would be a true Groupwise App. Activesync, while it has many features, nevertheless is a least common denominator solution, and also *is* often unreliable, if only because of bugs/incompatibilities in the literally thousands of possible mail apps (especially on Android).
If there'd be a true GW Mobile APP for Android and IOS directly talking to the POA (or some sort of proxy), I could switch off 99% of the GMS installs I support.
