Out of State Phone Consults & Prescribing

I have a 2 part posting here. Does anyone know if a medical resident or practicing physician can prescribe home medical equipment to a patient in another state? Assume you've never had an in person evaluation, and its only over the phone getting medical history and possible receiving email of pictures of their condition. The patients would be NON-Medicare. Only private insurance patients.

I am a working with a medical supply company thinking of recruiting flex time physicians for this type of phone consult. The product is a home compression boot commonly prescribed for lymphedema and venous insufficiency and/or stasis ulcers.

Is this legal? If so, is it something a physician might be interested in.
