Sure, but the concern may be with how easy it made it to share the contents of DDI. WotC seems to have much less of a problem with something like IPlay4E, which actively connects to it during use, but doesn't datamine and store the information outside the Compendium.
I will wait and see what the next Adventure Tool is going to be. On the DDI General forum there was a "soon" (whatever that is) answer at some point as to when the next Adventure Tool will be announced. It will be interesting if it overlaps with MasterPlan.
