There's actually a lot of work going on with PingPlotter right now - it's just not visible yet. We just moved to a new office and are hiring. Recent development progress has been agonizingly slow (believe me, we're not happy with progress either), but the outlook is good.

IPv6 is an important project - and growing in importance. There are some architecture changes underway that have been slowing things down, and these are still not yet complete. We're super-interested in getting IPv6 done, though.

Thanks for checking in.
