Ultra VNC

I am exploring this software as a Remote desktop alternative to crossloop.

Crossloop is nice but it is a little slow.

I have installed UVNC and played with it some. It seems easy to configure/use for LAN Remote use. I read that you can create an install package for WAN clients with zero configuration effort on their part(install and go). How do you go about creating this install file? and getting this to work across the WAN/Internet?

I assume i need to create a custom server Install Package? I also read that this file will only be a few MBs at the most.

Thanks for the Help!
