Don't ever let it be said that we don't listen to the voices of our clients.  
:-)  We've implemented a fix for this security issue that spans all of our 
Linux servers running ColdFusion.  Here's a synopsis from one of the techs 
involved in implementing the change:

"We actually run two J2EE environments - JRun and Resin.  While JRun does 
handle the Java processing for ColdFusion, Resin handles the requests for JSP 
pages and servlets.

Java implements a security policy system that can prevent access.  We have 
implemented security managemetn in the Resin server to prevent JSP pages from 
being able to read arbitrary files on the server.  We have restricted code from 
each customer's home directory to:

1) a lengthy list of files and directories that Java and Resin require 
internally
2) log files for the site and for Resin
3) that customer's home directory."

So, security in a shared hosting environment isn't exactly a myth, it just 
takes a little more work and flexibility.  If anyone needs a more technical 
explanation of what we did, please let me know via email and/or a post here and 
I'd be happy to assist.
