Hi Trustin

I am a old mina user.However,i was wondering why you vanished from mina
until i found out you were here.It is nice to see you again.
I want to start to try Netty because i saw the performance comparsion and
the Netty api seems more neat(naming,functions) to me.Most
important thing is,you, trustin.You always can answer peoples'question in
detail and more hit the point.Thanks.

After i browse the api roughly,I had some questions before I switched from
Mina to Netty.

1) Netty pipeline(i prefer pipeline to filter :)) has the boardcasting
pipeline? The one can do the encode and boardcast to all the channels.
Normally I did this in mina is do a for loop to send the same message to all
N sessions(N times encode).
2) The read idle and write idle methods are really important in mina which
could perform with heartbeat(ping) function perfectly.However,Netty's read
timeout 
pipeline function seems only in the beta version.Is it stable?
3) How does write time out really work in Netty?It is really important
feature since the server must deal with the slow networking client.
4) How does Netty handle the internal queue which means how to prevent from
OOM issue and fast writing(slow networking client) or reading.

The above questions are all based on my real case.Thanks a lot
again.Trustin.Good job.

Henry
