I wouldn't mind spending $20 for this ... it seems like a great tool and the reviews here are very good. The difference between $10 and $20 for the same functionality is negligible.

My only issue is that I would prefer to dual box on 2 separate PCs due to latency, frame rates ,etc. And from what I've read, that would require me to buy 2 licenses ... so, I'm spending $40 for a tool I would use on 2 toons when others are only spending $20 and using it for 5 toons (if multi boxing on a single PC). So, if I were to ever multibox 5 toons I would have to plunk down $100 to get the same experience as someone who only paid $20. Seems a bit unfair to me.

Any possibility of paying $20 for the first license and $5 (maybe $10) for each additional? This would mitigate the cost to something more reasonable, at least for me. Otherwise, it would seem to make more sense to purchase a hardware replicator.
