As for text messages/video/audio calls, they're all "bundled" in SIP. Hoever, text messages may not work with all SIP proxies (aka 'providers'). From free SIP proxies (that even give you free PST number) where text messages works, I could recommend sip.antisip.com.

Of course, it doesn't matter if you set own your own PBX at @home - then, whatever you want, will be working.

For noob-friendly desktop sharing on windoze, windows built-in RDP desktop sharing should be good enough. There is client for connecting to RDP desktop for Maemo, too.

Now, I understand the convenience of sharing desktop by "one click", but I also consider this a hell of security risk, especially, if build into application that is obfuscated as hell and no one knows what it is really doing.

They have collected data illegally, without informing users. Motherboard thing was just incident that leaked, they could collect, as well, literally everything from victim's PC.

If that isn't good enough argument, then it boils down to using any_random_software that is harmful, just because everyone else is doing so, and my heoroine (as in drugs) example apply.

Understanding and respecting.
