That would make (for the UK) 5billion non-spam/automated email messages
_every_ day, which is ludicrous, I don't even believe with spam we're
going to get to that for the UK market, (50 million peer 2 peer sms's
sent per day in the UK source is the Mobile Data Association)  So yes I
think it is comparable, of course it's a one 2 one (in general)
communication media unlike email which can easily be one 2 many so on
emails recieved you're probably right, but on sending I would put sms
higher.

but it's an illustration of how data use on mobile phones is something
people want, but as I say I'm not optimistic about SVG short term on the
mobile platform either.

Of course, but SVG is a tool, so if it's relevant tool to the market, we
should discuss it, and ensure that it meets the needs of that market,
SVG-Mobile does this (well maybe, there's some debate it would seem, and
I personally despite being a high mobile data user would never use
something smaller than a PDA for accessing content and I'm not a
developer in the area I couldn't really judge - IVR is as close as I
get.)

Definately!  and with many they are generally HTML/Javascript based
systems, so extending to SVG may well come in the future.

my iPaq supports tar.bz2 ...  the point is though that in downloading a
single static graphic for a 100x100 256 colour raster, there's not much
saving in a svg stream over the svg source, and the processing
requirements are a lot higher, so I don't see static graphics as relevant
to SVG mobile, but as I say, I'm not big on the industry (but have been
to a few conferences on the subject in recent weeks)
