This is a method for sharing a region between multiple players across the internet.

It is experimental and may contain errors.

Requirements
    Windows Vista, 7 or Linux (other OS may work if they can run Simcity and allow symlinks)
    Wuala with filesystem integration enabled (Linux guide: http://www.wuala.com/en/support/faq/c/19#id001912 )


Player 1 (moderator)

Create a group (public is okay)

Start SimCity 4

Create a new region

Move the region directory to the group
    Linux: mv ~/SimCity\ 4/Regions/[Region] ~/wuala/direct/mygroups/[Group]/
        Example: mv ~/SimCity\ 4/Regions/Test\ Region/ ~/wuala/direct/mygroups/SimCity\ 4\ Multiplayer/
    
Create a symlink
    Linux: ln -s ~/wuala/direct/mygroups/[Group]/[Region] ~/SimCity\ 4/Regions/[Region]
        Example: ln -s ~/wuala/direct/mygroups/SimCity\ 4\ Multiplayer/Test\ Region/ ~/SimCity\ 4/Regions/Test\ Region
    Windows: mklink C:\Users\[Username]\SimCity 4\Regions\[Region] W:\mygroups\[Group]\[Region]

Load the region in Simcity

Load a land area and start a new city. Save it


Player 2 (and more)

Create symlink
    Linux: ln -s ~/wuala/direct/mygroups/[Group]/[Region]/ ~/SimCity\ 4/Regions/[Region]
        Example: ln -s ~/wuala/direct/mygroups/SimCity\ 4\ Multiplayer/Test\ Region/ ~/SimCity\ 4/Regions/Test\ Region

    Windows: mklink C:\Users\[Username]\SimCity 4\Regions\[Region] W:\mygroups\[Group]\[Region]

Load another land area and start a new city. Save it


Have fun!

Try these examples to join a test region:
[Group] = SimCity 4 Multiplayer
[Region] = Test Region
[Username] = (your username on your system)

This method should work for any filesharing system, if the permissions are set correctly. One reason for using Wuala is because it sets these automatically.
