The present invention is directed to a system, method and program product that allows a user to acquire resources from a local computer during a session with a virtual universe. The method comprises selecting, from a number of image directions, to each of which a direction quality value is assigned, a direction of interpolation by comparing these direction quality values. In the case of phase change memory elements, the snapback voltage may be less than the threshold voltage of the phase change memory element. At the receiver, a set of two or more processors operate in parallel on two or more overlapping subsequences of the symbol data sequence Y, where each of the two or more overlapping subsequences of the symbol data sequence Y corresponds to a respective portion of a trellis. In one embodiment, the hash calculation for portions of received messages may be applied to keyed-hashing for message authentication.
