I saw a advertisement for a pull up bar on-line. It has handles similar to a TRX. From what I can see, these pull up exercises can be modified to a TRX easy. Austrialian pull up: http://www.perfectpullup.com/Workouts/Australian_Pullup.php and full pull up: http://www.perfectpullup.com/Workouts/Full_Pullup...

There was a previous question on the subject. Please see the pull-up description in http://community.fitnessanywhere.com/forums/p/247/263.aspx#263 . I have not yet tried. It is a little advanced to where I am in the TRX program.

I don't have an easy location to do wide-grip pull-ups where I live. There is a bar outside my house but it's on an inch or so wider than my shoulders, and has a wall on one side, which prevents me from doing a pull-up other than with a close-grip. I also do not have anywhere high enough to attach...
