Mac/BlackBerry SDK
ZBlackBerry is a suite of code that implements the BlackBerry USB communications protocol in a generic fashion. A few hundred lines of code let Macs use that protocol. A few hundred more allow multiple Mac applications to talk to a single BlackBerry simultaneously, something that has not been possible till now.
ZBlackBerry can also make a BlackBerry connected to a PC accessible via the same API as is used when it's connected directly to a Mac. This lets Mac application developers run their BlackBerry application under the Windows-based debugger and still have it communicate with their Mac application. This is a crucial capability when writing anything more than the most trivial application.
ZBlackBerry is part of ZooLib, our open source C++ library.
