I usually set a $MOTE envvar when using gomote, to minimize typing:

export MOTE=some-buildlet
gomote push $MOTE
gomote run $MOTE go/src/make.bash

I propose we hard-code this convention. All gomote commands that take a buildlet argument will check whether $MOTE is set. If so, it pretends $MOTE was provided in that argument slot. So all existing commands work unchanged as long as $MOTE is not set. If it is set, the commands above become:

export MOTE=some-buildlet
gomote push $MOTE
gomote run $MOTE go/src/make.bash

Opinions? @bradfitz @dmitshur
