Not that hard - probably a few days from scratch if you had no idea at
all where to start; less if you had some idea. At the end of that you'd
have a software solution running on something like FreeBSD. Of course,
to handle real customers, or thousands of customers, you would probably
need something more robust, maybe in hardware, and to run the thing as a
service, it would need to be bulletproof, well-connected etc. And of
course then there are the ongoing costs of space, power, cooling,
administration.... by the end of all that, it probably isn't looking
that cheap or easy, really. You would probably be talking tens of
thousands to set it up and run it in the first year.

Hm. Put that para together with this para:

...and you find the reason. It costs a bundle to set one up, but nobody
is prepared to pay for it. Same problem as IPv6 generally, in fact - but
they will be forced to go that way, while no-one is forcing tunnel
brokers on them. How many ISP customers have changed providers for IPv6?
I did :-) but I suspect I am very much the exception rather than the

If Australian customers were flooding to Internode in their thousands,
seeking IPv6, then the other providers would suddenly discover IPv6 was
worthwhile after all.
