(keitai-l) au/jphone java

hello,

plundering around with midp here trying to make a midp irc client and got a
few questions about kddi/au and jphone's java implementations:

1. are sockets supported, or just http (as the minimal specs of midp
require)? posting http requests for every update seems expensive (http
headers and such even when there is no data).
2. is the network blocked or can i thread it out nicely? on 503i phones the
whole thing froze while doing network stuff. :-/
3. where can i get the kddi/au java specs/api docs?... perhaps jphone too,
but kddi/au is most interesting.
4. oh.. and they both let users put home brewed apps on their phones, right?

i'm doing the typical "middleman" approach with a servlet or server-side irc
client that strips down and compresses the data from the ircd before sending
it to the phone's "irc" client. if anyone got some good ideas or anything i
should keep in mind, let me know. :)

thanks.

.tmk - living in the outside world for a few more months so please bare with
my cave-questions.
