and I can find no reference to it online beyond the initial posts on
the Xorg-devel mailing list (
http://lists.x.org/archives/xorg-devel/2010-September/012517.html)
Is it currently under any active development?
no-one is working on it afaik, last patches (sep 2010) are here:
https://bugs.freedesktop.org/show_bug.cgi?id=29905
given that we have smooth scrolling now, IMO mouse wheel acceleration
should be controlled more by the client side than the server, where it is
harder to get right, tricky to configure, and may not even work
consistently
across devices.

This doesn't quite make sense to me. Pointer acceleration in X isn't a
client specific function, and the mouse wheel is - ultimately - just
another pointer axis, with smooth scrolling expressing that properly
now. Surely with proper mouse wheel axes now, it would simply be a
matter of letting a pointer acceleration profile be defined for those axes?
pointer movement is application-independent, mouse wheels (and thus
scrolling) not. depending on where you scroll, nothing may happen, you
may scroll a line at a time, a word at a time, a page at a time, etc.
Putting any acceleration into scrolling obfuscates the physical
information from the device, quite likely to the detriment of the
applications that want to use it for their own acceleration methods.
Cheers,
Peter
