I'm developing dm-ioband, which is an another IO controller, and I
would like to hear your comments about dm-ioband if you have.

dm-ioband web page:

Dm-ioband is implemented as a device-mapper driver, so I'm proposing
dm-ioband to dm-devel and I hope device-mapper staffs take care of it.

Thanks,
