Yes, I should, as I've laid out an architecturally sound use-case for

Have you never administered a WordPress or vBulletin installation and
noticed that the HTML views are significantly more huge than the same
information when presented as RSS or Atom?  The redundant HTML present
in comment threads is just bloat, so I don't send it over the wire.

Or do you actually believe XSLT is slower than networking?  Nice pipe.

You realize this is not at all the case *yet*, right?  Besides, the
tradeoff on mobile where there is more transform latency, is less
bandwidth utilization -- guess I'm not seeing the problem.
