Good way to share large files

Google Drive is my preferred way to share large numbers of high-res photos or large video files (too large to email). With the ability to limit access to particular folders within Drive, I can determine who has access to which files. I would like to be able to cast directly to Chromecast from my iPad, but the app still lacks this feature. If it werent for this issue, Id give it a 5-star rating.
