A few things to keep in mind -
- IMO, wish list items that deviate from how Joomla! functions or how the MetaWeblog API functions are the type of thing that should be customized by the individual. That's the benefit of the GPL - you can take the work accomplished so far and adjust it for the needs of your organization.
I see the the "Configurable per-post author" falling into that category. If you want to avoid Joomla!'s security, that's cool, but I don't see the value in introducing that complication in a common extension. (You might also look at Joomla!'s OpenID and LDAP capabilities to solve some of these issues, still working within the J! framework.)
- Let's try to get some community synergy going here! I love this interaction, but, let's remember that Justo is not our code slave and let's be really sensitive to that. Especially considering his age, but also because we can contribute, too, towards the things we want for the common good. Let his work be the impetus for the contribution of others, as well.
Case in point - Justo provided us with an RSD extension. It appears Microsoft wants to use a different path. What a big surprise!

So, someone could take Justo's RSD extension and tweak it for the Microsoft approach if that is what they need.
Consider how quickly we can advance in this area if everyone does a little piece. I am not suggesting someone work on something that another person needs, either. But Justo gave a HUGE start here. If there are additions *you* require try to do that piece and share it back with the community. At least, try and ask questions along the way. Or, if that is completely impossible, at least spec it out completely. Or, PM Justo and offer to pay him for his work, then he can share it with the community.
Sometimes, we take advantage of our open source developers and we don't have to do that. We can contribute ourselves - and we can pay for some of this extra work, too.
Thanks for considering what I have had to say, I mean it with respect.
