Take a look at the few other client apps that require client daemons to
accompany in the background:

2) Sun CC (requires FlexLM, apparently)

Everything else is self-contained--even when there's crypto.  This includes
TrueSSH(damnit, I'm just going to start calling it this), Netscape-SSL, etc.

That being said, prngd is a really slick way to do what it does, and it
speeds things up significantly.  It's fast, lightweight, and well done.

I just object to it being mandatory.
