waaa, sorry for not fulfilling for the poll T_T
I've been busy with my school and just like 6hours ago I started to look for HDR mapping.. well.. I got the bloom and tonemapping working.. also the exposure thingyfoo...
These are not for this engine, just made the example code for mr. Ambassador, who is working on BlendX, a game engine plugin for Blender.
but here's the shot:

Yeahh.. it does not differentiate from the bloom so much apart from the fact that the colors are rendered in 16 point floating values and the amount of exposure is automatic and the shots are taken with the effect when you'd come from dark alley to bright scene in an instant (I quickly turned the camera towards lit objects from pit dark).
The testlevel is the regular 1000x spheres that are all around 300-600 polies (can't remember). Also this version does not use frustrum or LOD's.
EDIT: Here's new shot

This time I reduced the amount of bloom so that it looks "realistic"
