  Regarding speed test software, what are people running, and what do 
you think of it?

  It was surprisingly hard to find such stuff the last time I looked - 
right now I've got the guy who decide$ looking at the same software that 
http://speedtest.vonage.com appears to be running. Downside is that it 
requires Java.

  The stuff we've got (it was here before I was, 5 years ago) is 
definitely showing it's age - it doesn't even have the capability to do 
upload speed tests, and it's "quick test" while adequate for 1.5mb DSL's 
gets really flaky when you toss a 6 or 8mb/sec DSL at it.
