I tried fooling my Windows 98 computer's DNS - either by changing c:\windows\hosts.sam or c:\windows\system\hosts.sam - or by Network Neighborhood -> Properties, selected TCP/IP for my PCI adapter which connects to my cable modem, Properties -> DNS Configuration, Enable DNS, placed 66.11.163.212 and 66.11.163.213 in the DNS Server Search Order. Neither of these tricks worked, and yes I did reboot.
But I had published my site via FTP, and I went ahead and changed my registrar's DNS settings to point to TCH's.
The next morning, just 9 hours after making that change, the DNS change had propagated enough for me to see that it had worked! And FrontPage works fine using http. I'm a happy customer.
