I agree, it'd be nice to see. :)

If you've got users in a situation where all 30 of them are pushing
230kb/s through their link, I'll pass out from amazement. A quick check
of the traffic over our ethernet shows that our users (28.8 connections
with v.42) are pushing an average of about 8k/s each. Even with ISDN, I
wouldn't expect to see that go over 32kbits/second/user, unless you've
got 30 massively bandwidth hungry UUCP feeds going concurrently. Web
browsing is still idle-time intensive to read the pages.
