Are there any Feats that improve Blindsense?

[Pax_Chi]

I'm playing a Sacred Fist in a campaign, and they get Blindsense out to 10 feet at level 6. I was wondering if there were any Feats, such as those for Creatures or Monsters that could increase the range of Blindsense? Blindsense out to 10 feet isn't bad, but seeing out to 10 feet isn't quite as cool as the 30 or 60 foot Blindsense some guys get.

Edit: Futhermore, is there anything that can improve Blindsense to Blindsight?

Some creatures get tremorsense, which works so long as your opponents move and are in contact with the ground. That would be pretty sweet. Sonics are going to mess you up bad though.

There are some PrCs out there that grant Blindsense or Blindsight as their abilities. Note that anyone with the Darkstalker feat from Lords of Madness will counter you pretty easily.
