I do think that BOSH is an exceedingly good design. But, FWIW, I use
long-lived TCP connections over mobile networks quite a lot, and I
find they work fine, even when moving between cells. (I use XMPP, but
also IMAP and ACAP, all of which have server initiated data
transfers, or "push" as the media calls it).
As far as I know, the OMA are increasingly interested in long-lived
TCP based protocols, too, so the stability of mobile networks will
hopefully improve.
as rosters, avatars...). Moreover large amounts of binary data
exchanaged with mobiles are very unlikely, so I don't see the
necessity of making xml streams more complex for use cases that are
not well defined, if not improbable.
Right - I'll skip your discussion of binary XML formats (although
important), but I do want to pick up on this.
You're absolutely right - right now, exchanging large amounts of
binary data over long thin pipes is a very unlikely state of affairs.
I think this will change, primarily due to encryption, and - as a
much more minor issue - due to increased "rich messaging". (I'm
thinking about radio stations showing you pictures of the band now
playing, and such things, which certainly some mobile companies are
very keen on).
If the rich messaging doesn't happen, I won't be too bothered. If
encryption doesn't happen on mobile devices because it's too
expensive, I'll be very troubled indeed.
