Cable ( and ADSL) users are to limited with Upstream (upload) speed.
From what iv'e read on some article in a magazine (can't remember which) is that xDSL users are better of with upload speed than cable users. But for downstream (download) cable users better of. (exept Chello Amsterdam ofcourse)
The only thing is that xDSL internet is stable @ a continues speed, which cannot be said about cable internet.
Cable internet is just like the in the real world, on certain times there are traffic jams, which can drop your speed significantly.
I myself don't have to worry about that, im on ADSL, i can host up to 4 ppl with decent ping. My ADSL = 512 down and 128 up, on January 2003 they will increase my speed......only downstream however
to 768.
*SIGH* which they would increase the upstream speed rather than downstream. You know, in the beginning it was bad, 512 down and 64 up...
