And even 10Mbps is silly unless you have a DS3 connection or better.
A T1 is only 1.544Mbps, a DS3 is 51Mbps. I've never heard of a DSL or
broadband connection coming anywhere near either.
In theory Cable carriers local loops carry ~20Mbs or so, but that is to
be shared by all, so they cap you at the lower amounts so that everybody
gets something. In Raleigh where I live, Timer Warner does a decent job
of not oversubscribing the local loops (surprising since I live near the
NC State campus) and I almost always got 3.5Mbps downstream. Now if I
could only get them to give me better than 40K/sec upstream, life would
be perfect.
