Meeting sign language

Have you ever been in a meeting where there are perhaps ten or twelve of you round a table, maybe you and a few team colleagues together with management / clients / customers? Perhaps you are having a pivotal discussion about the future. You need to be in sync with your team to carry the day.

How cool would it be to have an in-house sign language to give your team pointers or more info about what you are thinking. The bonus would be you could have a subtext conversation below the main conversation but one where only your team understand it.

You might want to sign things like:

"I don't agree with them"

"I agree"

"We need to support this idea"

"We need to close this idea down"

"I need your support"

"Lets wrap this up"

"I think we need a break"

"We need to negotiate on price"

"This is going nowhere"

" We need to get back on track"

You wouldn't need a whole new language just about 20 or so key phrases to help out during the meeting. After all organisations already invent their own verbal and written languages, how about inventing an organisational specific non verbal language?
