In theory, yes, you can call "produce()" for each output stream with a different number of items (or, the same), then return gr::block::WORK_CALLED_PRODUCE to tell the scheduler that produce was handled inside "general_work()". I know of no blocks that actually do this, but I don't know everything. That said, the GR runtime internals support my statement & hence this is worth trying. If you do try & succeed, please do let the list know. Cheers! - MLD
