you -could- do it. but the thing is, it would most likely screw more
things up then you'd like. you'd either have to make a compromise on
speed (of both the computer and your client), or do as you suggest, with
letting the program call rc5des. -or- you could setup a mini
taskswitching environment, which would "work best" but cause the most
problems :) hehe.
