Roku's store includes a channel ( Roku Media Player ) which allows playback of local content, but playback of LAN hosted media relies on DLNA , meaning that my simple HTTP server isn't compatible on it's own. There are solutions (such as Plex) which could be used to provide DLNA support, but I didn't really want to have to stand up an additional service just so that the Roku could play content from a source that our existing media boxes handle fine.
