Peter Hutterer is the university student from Australia that developed Multi-Pointer X (to be found in X Server 1.7) and is responsible for a great deal of other work with X.Org when it comes to input and who now works for Red Hat. As of late, Peter has stepped up to handle many of the responsibilities with the X.Org 7.5 release and finally getting it out the door.
Peter had took care of issuing the first X Server 1.7 snapshot (and is working on getting X.Org 7.5 RC1 out shortly), pushed out new driver releases that he is responsible for, checking on the status of all X.Org drivers (mailing list message) to verify their X.Org 7.5 compatibility that in turn so far caused new snapshots of the Intel and ATI drivers, providing a large patch set that fixes DMX support after being broken for months (mailing list message), and has done a lot of other X.Org work lately too.
Peter's working on code and at the same time stepping up to see that X.Org 7.5 / X Server 1.7 makes it out into the world. Kudos to his work and the work of all other X.Org contributors.
