I strongly discourage using qlmanage to display the Quick Look panel.
"qlmanage -p" is meant to debug plug-ins (as stated by the man page) and is
really not suited to provide a user interface. In fact, it will give you a
very poor user experience:
1) it executes the plug-in directly (and does not use quicklookd), it can't
protect itself from bad plug-in behavior.
2) it does not provide all Quick Look panel controls
3) since it's a simple terminal tool it does not integrate properly with a
calling application (does not get any key events, can't correctly zoom
in/out, etc.)
Using qlmanage that way will be even more discouraged in the future.
Of course, I also strongly discourage trying to use any private framework or
private API to work around that problem as you'll have 99% chance to see
your application broken in the next OS release.
The best you can hope is to wait for Apple to provide a public API (and you
are welcome filing a report to Apple).

Exactly, an image view (IKImageView or NSImageView) + a HUD window is not
that hard to do.
