I think you're taking the whole 56K thing way too seriously. Sure, some people may kill them, but the majority don't. I could care less who downloads from me, as far as speed goes - however, while I try to stay up 24/7, I can't be held responsible for network outages that you might take as my having killed the connection. In addition, if I've recently recompiled my kernel and want to test it, I'm not going to wait 36 hours for an upload to complete - but that doesn't mean I killed the connection simply because it was from a 56k user.
