Despite the actions of our benevolent sponsor. WonderProxy, we still are in monetary-crisis mode. Because of this, our quotas have been dropped to half their usual levels. Expect downtime on a daily basis, probably after 3pm, EST.
If you would like help setting up your own server, we're more than happy to lend a hand. Just send an email to android2cloud at googlegroups dot com, and we'll get in touch. Alternatively, see server setup instructions on the Project Page: http://code.google.com/p/android2cloud/wiki/HostYourOwnServer
We're working hard to get a permanent solution up in place. We expect to have news on that front to announce in a couple of weeks. We apologise for the inconvenience, and hope you'll bear with us.
As always, suggestions and ideas on how to monetise a service like this (without resorting to ads or other yucky things) are always appreciated. They, too, can be posted to the Google Group.
