1) It may happen that the administrative module may ask for a
	nextHop which has is being removed from the finger
	table beacuse it just went down..
	Here the chord-node may return an invalid IP address
	to the administrative module..

	This can be easily fixed at the cost of a little
	waiting to be done by the administrative module..

	Let me know if such a problem occurs...
