TeamViewer

TeamViewer is a really cool tool. I guess the only software that might be compared to it from the point of ease of use is Ammyy Admin http://alternativeto.net/software/ammyy-admin/ or http://www.ammyy.com

I used a lot of software for remote help desk and for the years of practice I understood it's crucual thing to have ability to establish remote desktop connection in at the biggest 3 steps. Of course any installation or specific configuration are excluded, it will kill your business. So these 2 software seems quite progressive in this issue.

And one more thing unfortunately TV is absolutely not affordable for its extremely high price. So ammyy might be a good alternative.

TeamViewer is the best application I've found for remote desktop options without having to setup much stuff...it has a simple GUI and is free for personal use. I've used it many times to remote into a linux machine from another linux machine and it works just great. It does have a few drawbacks as you cant send keyboard shortcuts to the remote computer and you also can't pull up panels on workspaces that have them auto-hide...that is kind of annoying but not a deal breaker. Overall this is a great choice over vinagre or vnc as it doesn't require any port-forwarding or dynamic dns services.

@Deafboy , you said that there wasn't a Linux version and that is not true at all...I am using it as a native linux application as I specifically do not have Wine installed so the fact that it works without Wine even installed proves that it isn't dependent on it.
