I think the playing experience would be increased if there is always motion
blur in a multiplayer game to account for players that have faster
connections.  It always tweaks me to see a player disappear and reappear
several virtual feet away as I die from what seems like no reason except the
non-visual but all-powerful ping weapon.  At least with blur I'd see
something even if it is a stretched out player like the special effects in
John Carpenter's "The Thing" that has what appears to be several pikes
sticking into me.

hmm, why couldn't a card streak a tris or even a mesh for us? It would be
costly to blur in code, but wouldn't it be fairly cheap for the hardware to
copy the tris and just streaking the last few bits interleaved with bits
which form an outline of the form being blurred?  Actually, a proper blur
would probably take a sampling of bits across the mesh...I think a good
reference for the visual effect would be "Flash" comic books....just
multiple copies as in Mel Brooks' "SpaceBalls The Movie" when time is
compressed.
