I've still got to see the first install-less application. We have on average
1500 reports deployed with the application, several support DLLs of third-party 
tools and code, plus 6Mb. help files.

This is where the ship already sinks. I'll give you the 2 most common
- Many clients have PC-classrooms, where such things are simply forbidden.

- Windows Vista and security issues make installation and automated updates 
  a pain. Not everybody is allowed to do installs, they don't have admin
  rights and whatnot.

Nono. The IT people ask for it, because they want to be freed of the local
installations. Worse: once parents of school pupils are involved, the
problems increase thousandfold...

If you come and say this in front of my clients, I guarantee you that they
will carry you out, covered in tar and feathers, and drop you in the nearest
river :-)

I understand all your arguments, I have used them myself, but it is simply not 
my decision. So I try to save whatever is possible...
