I've been playing around with HDML 'n perl - I've created an HDML version of marginalia.org that I'll be working on as inspiration strikes. It is, I confess, mostly useless as links will not work, which rather nicely defeats the whole weblog purpose. I've never let actual utility stop me from doing things before, however, and I'm not about to start now. Anyone actually using this only gets 3 blurbs, due to the memory limits of the phones (I'm basically just using 3 as it seems to work; a more robust version would actually check memory usage).
