That's not what antialiasing is for...it is to counteract aliasing.

Such a glow effect would still be useful, and would pretty much have to 
be built-in unless POV is patched to output a high dynamic range format. 
One possibility is to make it part of a post-processing stage, similar 
in purpose to the MegaPOV patch but more flexible. (if such a 
post_process stage is available, it would be simple to add a filter to 
soften the edges of bright objects...people would probably just use the 
glow filter though)
(MegaPOV has a glow filter, but I don't think it does the exact same 
thing)
