Please tell me what provider is selling 100Mbit for $20-30 in the 408-532-xxxx
area of San Jose, California.

Currently, the only provider capable of delivering more than 768k wired
here is charging me $100+/month for 30-50Mbps maximum.

I could get 100Mbps from them, but they want $250+/month for that.

If I can get 100Mbps for $20-30, I'd jump at it.

For $100+/month, frankly, it's none of their business whether I'm pooling
my resources with my neighbors to pay for the connectivity or not.

Which is pretty much all that is available any more.

Not entirely sure what you are saying here. In this day and age, I don't see
any reason that wireless providers should get a free pass or be able to sustain
significantly worse policies than wireline providers. Wireless bandwidth is
rapidly approaching parity with wired bandwidth pricing at consumer levels.

Actually, providing a separate /64 for the provider link makes a lot of sense.
It really is best to pull that out of a separate provider aggregate across all
the subscribers in the same aggregation group than to carve individual
link prefixes out of each subscribers internal-use prefix.

For example, if you get a tunnel from HE, then, by default, you get a  /64
from our link block for the tunnel broker to which you connect and an additional
/64 for your internal use by default. If you click the "please give me a /48" checkbox,
then you'll also get an additional /48.

We do this because it makes our provisioning easier and allows us to support
users that want prefixes as well as users whose equipment (or brains) can't
handle more than a single /64 for their LAN.

There's really NOTHING to be gained from providing anything in between a /64
and a /48, so we don't do it.
