Vonage and Netgear are reportedly working together on voice over Wi-Fi products: They should be making an announcement on Monday, hopefully with some more details.
Voice over Wi-Fi could lead to a major shift in the way voice services are delivered to homes. Voice over IP is already growing in popularity, but a package that comes from two big names like Vonage and Netgear, both with an existing presence in the home, could encourage a significant uptake of voice over broadband users.
I'm curious about what kind of client device to expect. The most ideal solution would be a simple handset that looks and operates like a regular cordless phone. Ultimately a converged cellular/Wi-Fi handset would be ideal but for now that service is too complicated--it would have to be bundled with a cell phone service and it might not work in all public hotspots which could make the service appear weak to initial users.
