I think there's probably more users than ever. I guess what concerned me was that maybe someone's peer has developed a bug (like dropping reply packets). It wouldn't have anything to do with Gnucleus, but could impact all peers. I just wonder how easy it would even be to track down something like that.

It's happened before - I remember almost a year ago BearShare introduced a TTL bug that flooded the entire g-net for a few weeks. Now there's new peers being marketed heavily (and a few somewhat dubiously) of late, based on code licensed from others. It makes me wonder if they understand the impact of any modifications they may make as they didn't write the original program. After all, this whole ball of wax pretty much depends on everyone playing by the rules.
