Ok sounds trivial. Maybe I'd have that server side scripting glue
actually handle the request for the content (have it dynamically
manufacture the content for the http request)... this would avoid
possible collision over locking semantics; where the file was being
written to while apache was trying to read it. This would also let me
set the content-header so that the mime type was correct (as you
mention).
Then I'd post a link to that file on say my website and advise the
user to set the refresh update rate... which seems not too onerous.
To bad there's no way to just do it 'magically' where the user doesn't
have to do anything more than just click on the link.

Aslem,
Yes, but you'll need to create a "kml server". A simple
one (not intended for production!) is not very hard to make:
1. Install a web server application (Apache, IIS, etc)
on a server computer
2. Create a small program (e.g. using a C complier) to
build a kml file. This would re-create the file every so
often (e.g. once a minute) with updated coordinates. Put
the kml file in a place your web server can server it (eg
wwwroot, htdocs,...)
3. On the client compter, in Google Earth, do Add ->
Network Link, enter the URL of your KML file, select the
Refresh tab and select the Time-base Refresh to something
similar to the frequency your kml file is updated on the
server.
Of course, the small program in Step 2 above could be (and
likely should be) some web server compatible scripting
language (Python, perl, PHP, ASP, etc) or CGI program
running within the web server.
I can't recall if Google Earth is picky about the MIME type
the server sends. You may have to do some surfing re mime
types if Google Earth can't open the kml from your server...
