Efficiently browsing/searching through mp3 collection on attached NAS possible?

If i have a NAS with say,200gb of Music Files on it attached, will i Be able to Search for Files like i can in iTunes?
Is there a Way to browse through Files in a Way that i could linke in iTunes? Or like i can on the original atv2 menu under “Computer” when i browse through the iTunes Library on my attached Mac?

Native NAS streaming is not yet supported, but is something we're working diligently to complete.

Our initial focus is on video files, but support for music and pictures will be added down the road as well.

Thanks for the Input. What is your Time Frame for completion of this functionality?
