	Yes, that is what I'm trying to do (basically I have Java on one end 
and Python on the other). The Java is running on a Palm device, so using 
SSL isn't really prudent. This seems like probably the simplest way to 
do it, so this little problem is really bugging me. ^^;

	I tried Scott's suggestion, but it's giving me totally different 
results as well. -_-
