My IOGEAR GCS1782 [http://www.iogear.com/product/GCS1782/] KVM's keyboard emulation prevents many media keys (e.g., volume controls, music playback controls, etc) from being recognized by Mac OS X. To get around this, I'm using KeyRemap4MacBook [http://pqrs.org/macosx/keyremap4macbook/] to remap the keys.
