Google Cloud Logging

Not exactly the same, but if anyone is interested we just launched Bugfender a few days ago, a platform for remote logging/remote debugging on mobile devices (and later also desktop and JS web applications). It's still in a very early stage and so far we only have an iOS SDK available, but any kind of feedback is appreciated.

The beta is now open to the public you can simply create an account here: http://bugfender.com/
