After building up a good deal of buzz, Realmac Software has released Courier, a file sharing utility for Mac OS X that lets you quickly and conveniently share files on your Mac to multiple online services.
Courier’s interface revolves around ‘envelopes’, which are really templates for sharing to multiple services at once. For example, one envelope might be designated for your business’s Twitter and Flickr accounts, while another might be for your personal Flickr and Facebook accounts. Once you’ve created at least one envelope, you simply drag-and-drop the files you’d like to share onto the envelope and click Deliver.
Adding to its appeal, Courier integrates your envelopes with the Mac OS X Services menu (available via right-click or the current application menu), making it easy to share items from anywhere in Mac OS X.
A demo that allows five deliveries is available. Courier is priced at $23.95 as a limited introductory offer and requires Mac OS X 10.6 running on a 64-bit Mac. It currently supports Facebook, Flickr, YouTube, Ember, Amazon S3, Vimeo, and FTP/SFTP, with more services on the way.
