gpm's "-R" option means "repeat mouse info into /dev/gpmdata so something
else can read it without interfering with gpm's use of the actual mouse
device".  This option includes a specified protocol that it will translate
to... so the software reading /dev/gpmdata gets whatever gpm has
re-formatted the information as.  The default translation is to "msc"
(MouseSystems), so "-R" is the same as "-Rmsc".  Using that, no matter
what kind of mouse you ACTUALLY have, it will look like a MouseSystems
mouse connected to /dev/gpmdata. However, gpm doesn't seem to be able to
translate from and to just any arbitrary protocols successfully, so most
of us output as msc because it works (and that is the default that all the
howtos suggest using).

For me, the new knowledge was that you don't have to let it translate at
all... you can use "-Rraw" and it will simply pass on what it gets.  
While having the ability to translate to a common protocol is nice i am
sure, X is (now?) actually able to use more information from the imps2
protocol than gpm can. Finding out that gpm could pass on parts of the
protocol it didn't know what to do with was cool... though I remember
wondering why it wasn't that way by default when Mike Simons first
explained it to me.
