Okay, thanks for the explanations. Seems that I basically was hanging things up with my client, and thinking that the problem was with my server. It's all sorted out now, and works like a charm. I cleaned up my code a bit, too... threw some things into subroutines, and quit calling a long list of "my" at the beginning (which even I thought was ugly). I'll provide the "finished" versions if anybody cares to see how it wound up.
