sampling the received sensor data at a frequency indicated by the frequency parameter; and

providing for transmission of the sampled sensor data to the one of the one or more service servers requesting sensor data.

7. The method of claim 1, further comprising:

providing for display of a user interface, wherein the user interface allows a user to configure the association between the sensor data and the one or more service servers requesting the sensor data.

8. The method of claim 1, further comprising:

accepting a connection from a sensor apparatus providing the sensor data;

connecting to the one or more service servers; and

attaching the connection to the sensor apparatus with one or more connections to the one or more service servers.

9. An apparatus comprising:
