Yes, I would like to use the blur in Electric Image.
This yields more control and flexibility (if slower rendering times... but I love the flexibility :D)
And what I have been doing to fake blurred reflections, is to add the same reflection map to each reflective object and then blur each one, as each object requires varying levels of blur.
Problem is, if I decide to use a different reflection map, I have to change it in every object I added it to, which can get a bit laborious.
So it would be nice if each reflective object referenced the global map, but could set its own blur, strength, samples etc. on that referenced map.
Do you get what I mean?
