Many moons ago I was working with a startup developing a small battery-powered device based around TI's DaVinci DM355 SoC. http://www.ti.com/product/tms320dm355
We tried to use the MMC/SDIO interface to talk to an SD form-factor 802.11 card (since the USB was already assigned elsewhere), but I could see that USB working well for a cheap Ra-Link card instead. As to your question about pricing reference, the DM355 runs roughly US$20/ea from AVNet, for example. http://avnetexpress.avnet.com/store/em/EMController/Processor/Multimedia-Misc/_/N-100230/Ne-100000?action=products&advAction=&cat=1&catalogId=500201&cutTape=&inStock=&langId=-1&myCatalog=&npi=&proto=®ionalStock=&rohs=&searchType=&storeId=500201&term=dm355&topSellers= We were able to get a tray of sample DM355's from AVnet, and it looks like they sell some of the pkg variants in qty 1.
