This reminds me of when Steve Jobs named his computer Apple Lisa - http://en.wikipedia.org/wiki/Apple_Lisa

If the domain represents the product, it needs to be marketed so that everyone knows what Melissa is (http://meetmelissa.com/ ) which is available.

This way you can educate and provide an introduction of your product. Again you would really need to market that brand persona so there is no confusion that "meeting" Melissa is your home automation system.
