Sonic.net looking to expand FTTH to San Francisco

Californian ISP Sonic.net has filed an application to deploy street cabinets in San Francisco in order to deploy FTTH in the City. This could be an important development in a geography where few options are available to get good quality broadband. However, according to this article in the Chronicle, sonic.net could face challenges as AT&T has for environmental reasons. AT&T has been constrained in developing its U-Verse FTTC service in San Francisco due to these same issues with their cabinets. Note that Fiber cabinets are normally substantially smaller than copper cabinets and I haven't heard of any FTTH developments hindered by these issues, whereas other FTTC operations (like BT's) have faced such challenges. In any case, this is an interesting development that suggests that sonic.net's Fusion product is working and that theit FTTH trials in Sebastopol are promising... (Note: the Chronicle article is paywalled until later today, I'm hoping the url will stay the same.)
