How to broadcast the state of the digital pin numbers to the different nodes

[xhaju]

It may happen that, if I turn (let's say) Pin13 HIGH in my client page, the rest of the browsers might not update their behavior.

Could we share the state of the arduinos using the same dictionary used to broadcast the analog readings?
Something like: DCHANNELS='01000111' if channels 1, 5, 6, and 7 are HIGH.
