Yes. MINA is all about an abstract API, so you can implement a meta-transport that does what you want. > 2.

I'd suggest you open as many sockets as the number of cores of your machine at least, and each socket could host multiple sockets. If you can implement a virtual socket, then it shouldn't be that difficult to implement. It would be really a great addition to MiNA project if such a facility is provided out of the box. > Sorry for my english. Thanks for your perfect English.
