Can BitWise run completely without the server (in a pure IP mode)?
No, BitWise does not offer a pure direct to IP mode. The reasons for this are many, but the most important is that it would be difficult to incorporate it into the program without making the program needlessly more complex. Further, without being able to use the server for authentication, there would be no way to validate users as they “log in” and therefore the username system (and the reasonable assurance of who is on the other end) would be useless and unreliable.
