[rules-users] Questions about Drools, Eclipse, Guvnor

Hi, I've taken an look at the Roadmap in JIRA but, as I haven't found what I'm looking for, here I am :-). Today I read a message of Michael Anstis telling that BRL editor support has been dropped since 5.2, and I have a question: how do you see the future concerning rule authoring within Eclipse? Would you say that, in a near future, there will be only one authoring environment left - Guvnor? Or does Eclipse support has a chance to last and to be kept in sync with Guvnor? One last question: when working with Drools Eclipse plugin, I realized that it is not possible to declare custom operators, accumulator functions... so they appear in the drop down lists of the UI (or in the DRL suggestion engine). Is it the same in Guvnor? Thanks in advance for your insights, Cheers, Bruno.
