In After Effects, I believe it is called 'video echo'... That is a good place to start. Then if you can matte out everything but the color range that the trails are making, and layer that back on top of the original video, so that only the trails get blurry!

Great.. It worked alright in a quick test.
So..

I duplicated the original layer
Then applied time echo to that layer - settings (echo time 0.02, number of echos 9)
Then colour keyed any red bits and other background bits out.
Then set layer blend mode to screen, and layer opacity to 80%

Thanks!
