Many of us are designated "family IT support", so remote controlling your family member's PC is a standard evolution. Unfortunately, most of the ways to do it suffer from a lot of issues - like requiring Java, requiring a monthly fee, installing weird software, disabling firewalls or security software, etc.
I just tested this across my COUNTY (work) network - and I was able to get in and out - which is a miracle.
Not just remote control like GoToMeeting/PC - but file transfer and stuff too.
If you even remotely (ha, sorry for the pun) need something like this - check it out. As a bonus, this sucker doesn't even have to be INSTALLED - you can one click download/run from the website and execute it without installing.
Did I mention it's totally free for personal use?
What a crazy deal ...
