Not *that* may be very true, and your GUI indeed looks very very promising.

You'll find this work orders of magnitude easier than convincing people that we need yet another profiling system in the kernel. So I urge you, keep the cool gui but adapt it to oprofile. I'm sure John will be more than willing to work with you to make sure oprofile supports/will support everything you need.
