$49 per machine is a pretty high cost, particularly for something which is new and untested. I'm no expert, but my gut feeling is that for this kind of tool - you need to offer a more 'enterprisey' offering. The way budgets for the kind of places that this tool would be useful are allocated, $49 for a single utility for every machine it might need to be run on is something that sysadmins might have difficulty explaining. Bear in mind that the idea of syncing is not novel, and most sysadmins have built their servers around the current tools and constraints available. They are likely to look at your utility and think 'that's cool, but it's not worth the cost: what I have now works even if it takes longer, and I'm not paying anything for it'. If you asked me to pay $49 for a faster version of rsync, which I then had to incorporate into my tool-chain, I'd probably just forget it. The cost of changing to a new utility is more than just the cost of the utility itself.
