I'm going to start posting projects on my website. The bit where it gets weird is I want each project to be a page (probably with subpages!), but I also want each project to appear as a post, so it shows up somewhere in my blog and my RSS feed. I'd prefer to just have one entry with the post content, so the blog post for my page has the exact same content as the page itself and I don't have to repeat myself to do that. (I'm a developer. I'm picky about DRY).
What I'm picturing is something that lets me create an empty post and say "this post is actually a proxy for this page," and have the necessary magic (including in the RSS feed!) happen behind the scenes.
Is there a plugin or some commonly used pattern for this type of thing? If it works in another direction than I'm picturing, that's cool too.
