Clearly, we are looking at git here, not GitTorrent.

All data producers and data consumers *in git* use band #2 to transport error messages and progress report. GitTorrent cannot not talk to upload-pack or upload-archive and expect to get arbitrary binary data over band #2. For use-cases that you have in mind in GitTorrent, the *protocol* may be a good choice, but the current implementation is definitely a special case. -- Hannes -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
