Hi,
Good question!
unfortunatly, the next step for optimisation with this, is to script the various rpc themselves and not rely on sending actual playmaker global event via the playmaker support for pun, because then we can't rely on their names.
you can then always send back a global event upon reception of your custom scripted rpc, but at least you control the rpc handling fully with your scripts.
The cheap hack is to make global events with one letter only, and then you are close to optimal optimization before moving onto scripted variant.
Bye,
