Narrative:
I was flying a hawker 800A. We were cleared for takeoff approximately 40 seconds after a stretch MD80 was cleared for takeoff on the same runway ahead of us (runway 27R). We taxied into position slowly to allow some separation between us and the MD80. As it was; the MD80 appeared to still be on the runway when we began our takeoff roll. We were light and believed we could takeoff before and out climb the MD80's flight path or we would have asked for a delay in position for separation. Winds were variable and a windshear advisory had just been issued. At about 50 ft AGL we experienced a wake turbulence roll to the left that required full right aileron. In spite of the full right aileron the aircraft turned slightly left of the 27R centerline. We were asked by the tower why we appeared to be turning. We advised it was due to wake turbulence. We had several distracting calls from the tower during the initial climb; while we were still in light wake turbulence; including a request to call the tower when we land and a phone number. It is important to note that while it may have seemed to the tower that we were drifting left; the needle for the FMS displaying the SID we were flying remained centered at all times. Two important comments: 1) tower [controllers] must be required to allow for more separation between takeoffs; especially for smaller aircraft. 2) tower [controllers] must not make repeated non-safety-of-flight calls to aircraft during critical phases of flight; especially when the aircraft has expressed that they are having an in-flight issue (wake turbulence). The pilot distractions caused by the tower in this case did not promote the safety of this flight and actually inhibited it. They knew my destination and could have called there to ask me to call the tower. My only regret is answering any of the tower's calls; such as the request to copy a phone number.
