One problem is that if I want to include a server in the scheme, all the prices go up by a factor of 10 or more. I find this obnoxious. I'd rather have data caps, or charge per GB to make it fair. I don't need the software and the storage to be from the same source. But this price disparity applies equally (or worse) to software-only vendors. Example: GoodSync. $30 per license on a PC, but $1,000 per license to run on Windows Server.
