ChunkVNC vs. Teamviewer

[JulianLE]

I discovered ChunkVNC with the Instantsupport-compiler and it's really great, because easy for customers, fast and small. Nevertheless I wonder, whats the main difference between all the UVNC with repeaters or echoservers and Teamviewer?
In some cases I can't connect to the customers PC with chunkVNC, I guess, its a kind of 'intranet' on his side. To reproduce that, I tried to connect to my own companies PC when I'm logged in via URA (Juniper networks) in the intranet and I had no chance with all the free stuff, but Teamviewer was able to connect from ouside the intranet.
I'm not really familiar with the details, but I thought, Echoservers or repeaters are the key to manage this? Would it help, if I offer the repeater on my PC as a webserver under Xampp? Is this possible? If yes, I surely need another file than the repeater.exe or distributor.exe to run it at the webserver, but wich one?
Any hints or links to explanations are welcome.
Thanks
Julian

If your repeater is set up on a publicly accessible location, with ports open, then it should be just as usable as TeamViewer and LogMeIn et al.

The only thing that might get in the way are restrictive local proxies or firewalls that do NOT let you communicate directly with the outside world via NAT. There is some work being done to bake in http proxy support into ChunkVNC, but I don't think it's done yet?
