Can MINA do more?

[David Lee]

Hello all,
I want to write a high-concurrency server with event-driven style,
can MINA do more beyond realizing protocal? In other words, can I write my
service on MINA?
I think I can also creat my IoSession to hold my service state. and event
handler for service event.
Have anybody try like this?
