Once Jetpack integration is released and you are able to embed media items from your cloudup account, wont that effectively be a simple CDN. Would be very interested to know where the media files will be served from ie single location or multiple locations - if a single location in USA, then that will increase page load times for our European clients. However, the possibilities to expand the service into a full CDN are there and that would be a brilliant inovation.

As for the comments about people (especially large companies) wanting to "own their data", then this is no different from any mainstream CDN company.

Finally, in answer to the person worried whether Automattic will be around in 1 or 3 years time - think we would trust that more than most other businesses !
