Thanks for the link to that resource! It should give me many hours of entertainment!
In the mean time, I've encountered an in-world location monitor that advised me that my AVI was presenting a significant performance impact. With some investigation, I determined that my hair (!) was requiring a 10K script support. Now, I'm a responsible Netizen, so this left me chagrined. I set up the hair prim to my best adaption and removed the scripts (via the provided HUD). Since then, knock on a wood texture, I've not had problems. Is it plausible that a +10K script load (over the ~3K load my presences presented after clean-up) could shut down a login as just the sound was coming on?
But, as a Cyber denizen, I enjoy the challenges!
P.S., appreciate the unexplicated reference to 'traceroute'!
