How critical is it that this application work completely offline?  I
suggest that you seriously consider making your application crippleware
unless it can "call home" -- that is, certain key bits work only with
online access even if the majority of the app is local.  This may or may
not include the secure database, but if the data is local, it can still
get hacked.
