pattrstorage outputmode 3?

Jeremy,

Pattrstorage's outputmode 2 proved quite useful in a network
situation, where only single values are sent and received.

I ran into problems with continuous control data though, mainly
because of the inherent delay of the network, i.e. the data from the
network don't match the values stored internally and are being routed
back to the network. Now, the remedy would be to add another
outputmode that would function as follows:
When input is received from the inlet of pattrstorage, the object
behaves as if in outputmode 0, i.e. no output;
when input is received from the clients of pattrstorage, the object
behaved as if in outputmode 1, i.e. output.

This way, I could differentiate whether the input is internal
(client) or external (network->inlet) and only pass data generated
locally to avoid feedback.

Would this be difficult to add?
