I don't buy the bandwidth argument. This kind of thing doesn't even appear
on the radar when compared to bittorrent or RSS traffic.
The processing power doesn't seem like a big thing either -- comparing
strings is not that expensive, and you have to do it anyway, to test for
data integrity and prevent invalid data from being submitted, etc. Not to
mention that you'd have to do the comparisons anyway to support down-level
clients.
