Yup, sucessfully installed with dynamic IP from Bell Advantage Business Network - same as Sympatico residential.
Step one: arrange dyndns.org account and everydns.net account
Step two: arrange to transfer domain to everydns nameservers
Step three: install e-smith using dedicated option - PPPoE connection type - dyndns.org service.
Step four: Test internet connectivity - this will activate your IP on your dyndns.org account
Step five: Set up your everydns to point
www.yourdomain.xxx and yourdomain.xxx as CNAME to youraccount.dyndns.org. Set up at least one MX record pointing to youraccount.dyndns.org
Step six: Set up a virtual domain under e-smith with yourdomain.xxx as the domain name and an ibay for the website.
That's it - it was dead simple and so far I'm liking the ease of maintenance that this option provides.
