We already have something like this, two years ago a masters student
created this. It however never made it into ocl-trunk.

Checkout the DisplayImageComponent at:

svn.mech.kuleuven.be/repos/orocos/branches/ocl-pma/vision

I don't know if this is what you are looking for but it inherits from
the OCL::ReportingComponent and can display images from multiple
sources in a separte thread.
It has been a while since i checked that code. If it doesn't work
out-of-the-box it should at least give you a serious hint.
