What interrupts and timer resources used by the Tlc5941 library ?

Can't find any mention anywhere (yet) of what interrupt and/or timer resources the Tlc5941 library uses.

I tried using it with the VirtualWire library, but that didn't appear to work because both libraries thought they had control of the same interrupt source perhaps. Correct or no ?

What libraries is this Tlc5941 library compatible with ? Which ones won't play well on the same arduino ?

I'm hoping that I can get SoftSerial to work with the Tlc5941, get it to receive commands over a wireless connection, and tell the Tlc5941 to fade+change colours as directed by the the incoming command. Has anyone done this already ?

Any links to docs where each library lists it's hardware resources/interrupts/timers much appreciated.

TLC's use SPI and not serial, they need 3 or 4 pwm signals, so thats 2 timers.
