I've setup the bug and feature trackers in SF.net. I defined meanings for categories and group artifacts.
Categories: API, Protocol, Platform and Installation
Group is simply the jnetpcap version number the issue or feature is related to: Version 1.0, 1.1, 1.2 and the future 1.3.
This should make it easy for people to lookup bugs in any version of the software or feature and in which version it occurred or the feature is expected to be included in.
