Steve Woodcock's on holiday for five days, but when he returns you should definitely coordinate with him. Your package builder, for instance, can build up all of the metadata needed by his package instantiation code. He's not quite done with his changes, but you can look at what he's done thus far. Also a "package creator" exists in ACS 4, he's just beginning to look at it. I haven't, yet, maybe I will find some time later today (though I've got some APM and site map loose-ends to take care of first).
Another thing I've noticed with packages is that various programmers were lazy and didn't bother to create all of the metadata that tracks attributes and the like. Some packages are complete in this regard, but most aren't. A package builder could be a big help here, removing a bunch of the tedium involved with the task.
