Why yes. These tools are quite expensive too. They are called "lawyers".
Alternative answer: Why do you think you need to peek inside the .bit file? You know, the bitfile that your chosen fpga vendor (who generally has a bigger legal department than the average user) doesn't like you to reverse engineer.
Is this in the same project that you need ICAP for?
Just open it with some bit-wise text editor (like ultraedit). The info inside corresponds directly with the configuration frames detailed in Virtex-5 Configuration Guide (I always reply you with the same phrase )

Indeed, and with a lot (and I mean A LOT) of energy and time (especially) you might be able to interprete, what's inside.
Just some indicators:
a bit file for an average FPGA has about 10E6 bits ....
