It would be really handy to have a configuration that would enable me to be off-line between 9am & 5pm (for example) (just realised you'd want a day selector too, wouldn't be needed at weekends).
I occasionally work from home and on a few occasions I've been mid way through a webex demo and had an invite pop up because I forgot to close RTP, so having a way to have RTP off-line automatically during a work day would be great.
