I look forward to the day Aruba spends less effort making excuses for their lackings and instead direct that effort to debugging, documentation, facilitating customers requests.
Raouf,
I understand and respect your request. We have the same needs in certain areas of our campus. Be aware just because Aruba can't meet your needs in this area does not mean that your needs are not valid.
We were able to accomplish a campus split-tunnel solution using Cisco's new distributed controller model (controller service built into access switches).
We use multiple vendors depending on how a vendor can meet OUR needs. Our needs do not change to facilitate any one vendors short-comings.
Good luck in finding a solution,
Fred
