Oh, you're talking about not just install-time relocation, but run-time
You can use GHC like this on Windows, and you'll still be able to do that.
But GHC is unusual in that it doesn't need any registry stuff to run:
most Windows software needs to be installed on the local machine before it
can run at all. I've never seen anyone just mount a remote drive for the
purposes of running something during a presentation - normally you'd use
RDP or VNC or something, or on Unix, SSH to the remote machine.
You won't be able to use Haddock from an ad-hoc remote mount, at least not
without giving it an extra argument or setting an environment variable to
tell it where to find the package.conf. Even a dynamically-linked
ghc-paths won't help here.

Not necessarily - how often do you need to run Haddock against something
other than the libraries for your most recent installed GHC?
