I'm not a fan of outliner software personally, but I do keep yelling at them* to support Markdown or Textile so I can compose and send my e-mails straight from vim. One of the beautiful things about Posterous is that it is basically just... email! So if a standard syntax like textile or markdown were supported, you could write it in whatever you want. In your case, you could write it in OPML, write a script to convert it to textile/markdown, then pipe it to sendmail. Done! * "them" being Garry, because everything is really his fault. Sachin is a good guy.
