Vivato's filings for its VP2200 802.11g switch were approved by the FCC today: Filings show the antenna has a theoretical maximum 48.1 dBm EIRP which is a measure of its effective signal strength. The VP2200's manual says that it supports receiving Power over Ethernet (although it's not 802.3af).
The Ethernet ports are just 10/100 Mbps, not gigabit Ethernet, which is slightly surprising. It appears to have six separately configurable wireless interfaces, each of which can be set to a unique channel or which can be set in multiples to the same channel. However, all the interfaces will be set to the same channel for practical deployment.
The VP2200's manual also shows the full command-line interface, including configuring multiple VLANs, but makes no mention of WPA at all, only WEP and 802.1X/EAP. The manual shows a Wi-Fi seal, but it should be uncertifiable as a new device without WPA.
