It seems Orb is geting a lot of press / coverage since opening up their APIs and rightly so, this is a perfect example of doing things right in my opinion, much like the mighty Flickr and means they will probably go on to make decent money and provide a compelling and good service in the meantime.
My company has been working on this for nearly two years now and is still not releasing anything, the demo has been going through three job changes for me and still it's not on the market !
In the meantime Orb has developed a similar system, released it and gone on to open up their system which is something that will never happen for us even when we do get around to releasing it
