Yep, I customize my browser toolbar too, very similar to yours which is nicely done.
What I'm getting at is a set of links that would be handy when you're at iHub specifically, that reside just at iHub, and that you don't want to devote real estate to in your normal browser toolbar.
Some benefits:
-you wouldn't have to replicate your financial links in all browsers that you use (sometimes I use IE, sometimes Opera, sometimes Firefox). Just add it to the iHub bar and it's always there for you
-you wouldn't have to replicate the links in all computers that you use (work desktop, home desktop, laptop)
-the links would be available even when using public computers
-I haven't tried cellphone access before, but maybe it would help there too.
-If it's a premium feature it could help subscriptions.
-If you share your computer with someone else, you won't have to fight over the browser toolbar real estate for all your iHub related links.
I think it would be a great feature, but it's possible iHub just can't do it for technical reasons.
