Routers, switches, frame relays etc etc are NOT free, hence the (limited) bandwidth that flows through them is also not free...

I couldn't agree more with you Dooby
Backbone bandwidth isn't much of an issue here though, it's the access routes to the backbone that become congested moreso.
Anyone know the current backbone capacity of NTL, including its transatlantic links?
With ISPs moving away from Synchronous Digital Hierarchy (SDH) technology to running networks based on Dense Wavelength Division Multiplexing (DWDM), a great increase in bandwidth can be achieved. 2.5Gbit/s backbones are quite standard/minimal with DWDM, since with the appropriate equipment attached to the same fibre, capactities of 10Gbit/s are easily achievable, even increasing upto 40Gbit/s +- the equipment is expensive though, so if users want this, they will have to pay top dollar
Anyone know of any networks running in excess of 10Gbit/s at the mo? From conversations I've had previously, very few ISPs are interested in reaching these capacities just yet, since even those that have 10Gbit/s with lots of customers find that actual usage is a mere scratch in the overall achievable capacity.
