thx, I'll try it out in a few day.

:)

Maybe you'd like to try it out. You need:

a) libmixp:	http://releases.metux.de/libmixp/
   (it also includes an little cmdline in the cmd/ dir)
b) libmixpsrv:	http://releases.metux.de/libmixpsrv/
c) libgpm:	svn://svn.metux.de/public/gpm/libgpm/	(use latest tag)
d) gpmd:	svn://svn.metux.de/public/gpm/gpmd/	(use 9psrv branch)

Well, then use another simple-text-parsing function of your choice ;-o
The major point is that evrything goes through an _simple_ text 
representation, so things like typesizes, bytesex etc are irellevant.

Both protocols could be optional (via --enable-* switch), so user/packager
can decide. Or the old protocol is simply provided by an proxy.

I'll have a look at the gpm-2 branch and check what's changed. 
But at least there should be an backwards-compatible libgpm.
