Looks good Stephen! I'll get around to coding up a login packet function 
for 7.0 this week sometime.  Then we need to get a capture of the 
acknowledgement stream to make sure we're doing things right.

There must be a function of some sort to go from clear to encrypted text 
that just isn't all that apparent. *shrug* maybe someone with an crypto 
background can look at it.
