google earth
I have a street network that has been extracted from AutoCAD DWG's and converted to a KMZ file. The resulting polylines, when launched in Google Earth, do not visually align with the imagery.
I am not sure what the source data is, and not really concerned with anything other than realignment (transformation?). I have ArcExplorer but no other GIS at the moment other than AutoCAD and Microstation, which aren't true GIS platforms.
Apologies for the rambling, post, thanks.
When constructing a custom KML network link using Manager, the KMZ file is automatically copied to your virtual root directory and is available at http:/// /kml for everyone to access. Simply open this location in a browser to view all the custom KML Network Links for your server.
for ArcGIS 10 Server
Click the Services tab in Manager.
Click KML Network Links.
Click Create Network Link.
Specify the name of your link. The name will be embedded in the Name tag in the file and will be used as the file name. Optionally, you can provide a short and long description. The long description allows embedded HTML tags and URLs.
When you've finished typing names and descriptions, click Next.
Choose the map service for which you want to create a network link. Map services for which you have disabled the KML capability are not available.
Check the layers from the service that you want to include in your network link. By default, all layers are checked.
Specify how the layers should draw. The first two options will return rasterized representations of your vector features. The third option will return the actual vectors. Once you've finished setting this property, click Next.
Set the Refresh, View, and Hostname options according to the way you want the network link to behave. The default options are sufficient for many network links.
Optionally, use Google Earth to edit the link, enhance its properties, or embed it within a new link. You can save the enhanced link as KMZ, then use the steps below to publish it back to your server.
How can you find the URL for a particular service?

QGIS will not save/export straight to KMZ. As Aaron suggests in his comment above, you can right click on your layer in QGIS, select 'Save As...' and choose KML.
To then convert your KML to a KMZ, you have two options:
Open the KML in Google Earth, right click on 'Save Place As...', and select KMZ as your desired format.
Put your KML in a .zip file, then change the file extension to .kmz. You will now have a working KMZ file you can open in Google Earth as normal.

If you look at the data in Google Earth, right-click a feature and choose properties:
Then, while the properties dialog is open, you are in an editing mode. The cursor will change and let you move points of the feature:
The one caution is that I don't think it keeps connectivity to adjacent features, so don't move end points if you want to keep a topological network.
This is - of course - all assuming the lines are only slightly off, and that you want to edit them manually into position. If they are a large distance away then consider that the original coordinate system was somehow wrong, or if they are all a consistent distance away then maybe they need an offset?
