Jun Ma recommended (via private e-mail) the HWg-STE, which appears to be a small, network- attached box that accepts 1-wire probes. He included links to their international web site (hw-group.com), as well as the Canadian distributor (hw-group.ca), but no prices are listed. I've e-mailed the Canadian site, and will see what the price is.
Just heard back from them. The price is US $195 for the HWg-STE with a temperature sensor, and an additional US $105 for the humidity sensor. Looks like the MicroGoose is still the cheapest way to go for a packaged, plug & play solution.
