yeah, you can edit the CIV4DetailManager.xml (all of them - there's one for the main game and one for each expansion) like this:
Code:
<Fader>
<Name>CAMERA_MAX_DISTANCE_FADER </Name>
<!-- <Value>0.75</Value>
-->
<Value>0.5</Value>
</Fader>
The stuff in comment quotes ( ) is the original value.
[edit: misunderstood how the value works]
The smaller the value is, the farther you can zoom out.
you can make the value even smaller, but then you'll see large parts of the map twice, since your viewport is larger than the earth circumfence. :)
i think there's a setting that specifies when the map is actually wrapped on a globe, but i don't really know which one that could be.
