Send data from phone to phone over internet?
<p>Is there any way to actually communicate between two android devices over internet without having to have any service between the two devices? </p>

<p>Like posting something to device2 from device1 without having to "middle-land" on any other server or whatever?</p>

<p>Another question: I tried to ping my phone over the internet (simply using the IP address), which didn't work, since it seems like my ISP shares the same WAN-IP for all the phones or at least a few of them. So is there any way to actually ping or send data to my specific phone just by using the IP or my Google account or something?</p>
