Nothing I could do either. I didn't mean to imply "rolling our own" 
crypto package (ref Ted's msg). I was thinking more of porting one 
already in use. And perhaps it wouldn't have to be "top-of-the-line". 
However.... If there is nobody capable / willing to do that and the 
only real use for the larger PRNG code *would* be for a crypto 
package, then I don't see a particular advantage for adding the 
larger PRNG code. ....Though I would argue that the mega128 can hold 
an awful lot of code... :-)

Agreed that it is heavily dependent on hardware. I thought I 
remembered seeing stuff on one of the lists about possible ways of 
generating seed values. And documenting it might still be useful... 
But I would put it at a low priority.

Well anywho, my 2 cents.
