Given an X client window ID, is there a way to move that window or change its geometry from the command line?
$ xlsclients -a
Window 0x3000001:
Machine: ohm
Name: Terminal
Icon Name: foo
Command: foo
Instance/Class: foo/bar
$ xmovewindow -id 0x3000001 --geometry +100+200 <-- this is what I would like to do

I think xdotool will do the job.
E.g.
will focus the window with id 0x1a00ad2. There's also a windowmove command which is probably the one you're looking for.
wmctrl is slighty more advanced. It is compatible with EWMH/NetWM X window managers as you can read on their website. I don't think you'll need it to be compatible with those though.
