Which is why the very next line of my post read:

Setting TTL so low without good reason is verging on net abuse, IMHO.
And yes, it won't work for at least one very large pseudo-ISP, as I 
understand it.

But how long would you hold on to your account, once the ISP realises
you're running servers on a cable modem line?

Relevant terms here are "aggregation", "shared bandwidth", and "business
model".  If you want real bandwidth, you have to pay for it - and it's
expensive.

Even if you are allowed to do it by the ISP, you will not be getting 
quality of service.
