that can work, however XML output may not be too bad, people entering commands manually are probably not going to be asking for that much data. the biggest problem I see with XML is the need to send requests and responses via e-mail for debugging. if one end uses a HTML enabled e-mail client it may not work well to paste XML text into it.
