Hi everyone,
I'm one of the devs on this app, just ran into this and I figured I'd try to answer some questions. Hopefully this isn't considered spamming the forums
Does the app work over 3G? Yes, if you configure your router appropriately though I would recommend against doing that right now. This is a top priority for us (right behind implementing audio) and in the next release or two we plan to implement a real "over the Internet" mode which removes all router and IP configuration headaches. We'll probably make it so you can use your Gmail/Facebook/Twitter for authentication (we will never see your password) and then you will automatically connect to your machine. Naturally, the "direct connect" option will also remain.
Does the app have audio? Not yet, but this is #1 on our priority list and we'll work on it right after the iPhone upgrade is out the door. It will come in the next two or so weeks. We know this is an important missing feature.
Does the app survive a system reboot? If you configure your system, it will. The server is a single "thinstalled" executable without any bloatware or spew of files all over your machine. In the future, we do plan to make the "install as a service" more of a handheld option. At the same time, we want to stick to our philosophy of having very light software.
Finally, we're currently under way with our beta for a large release which include the iPhone version. If you email us (email on our site everyair.net - board isn't allowing me to put it here) I'm happy to add you guys to it. For those of you that want to try it out for free, that's also an opportunity to check it out.
PS - we really appreciate and want customer feedback so feel free to let us know how to improve.
Thanks,
Nick \ everyAir developer
