Not so long ago there was a good alternative to Skype - ooVoo video messenger. He was able to show the desktop in dynamics, transfer files, allowed video conferencing up to 12 participants, had good image and sound quality. I used it for a couple of years, having switched to it from Skype, which just then went sour. But... ooVoo stepped on exactly the same rake as Skype: from version 3.7 it immediately jumped to version 7.0, which turned out to be completely non-functional, while the ability to use older versions was forcibly disabled. I had to go back to Skype...
So that leaves Tox. But it does not have a screen sharing in the stream, there is only the transfer of individual screenshots. But it does not require a central server and is well (according to rumors) encrypted - both of these factors are some guarantee against wiretapping.
