Files are files. Streaming is just your hardware moving a file. Given the terse request with no details about what would be playing the content the answer must be no.
But there are numerous NAS or file servers that you can play a file on your laptop. But is that streaming?
I am wondering if their are routers out their, specifically the 'Netgear WNDR3700' which have the option to attach an external USB drive to itself and then have the power to pump out streamed HD content, from that USB-Drive, over it's wireless? Without any hickups or anything...
Also a plus would be if it could do the above and also have somebody doing casual Internet Browsing through wireless as well.
