atv flash sharing media with xbmc

Is it possible to share added afp connections and shares with xbmc?

I can’t still access afp through xbmc so I dedided to buy this piece of software fot the purpose.

It works well and reads subtitles but the bonus of xbmc is that downloads subtitles in runtime which saves me a lot of trouble.

If not, is it a feature defined for next deployments (download subtitles on atv flash media player)?
