The MIT LCS Computation and Biology group and the MIT Center for Genome Research support two experimental tools for cross-species comparative analysis and gene recognition:
GLASS (GLobal Alignment SyStem) is a tool for aligning pairs of homologous sequences. It is designed for aligning long, divergent sequences, that contain blocks of moderate to strong homology, such as orthologous/paralogous pairs of genes.

Rosetta is a tool for predicting coding exons on a target human sequence (may also work for other mammalian sequences as targets), based on comparison with a homologous sequence from a different species.
We are currently updating Rosetta, please check back soon!
GLASS and Rosetta are both described in:
S. Batzoglou, L. Pachter, J.P. Mesirov, B. Berger, and E.S. Lander. "Human and mouse Gene Structure: Comparative Analysis and Application to Exon Prediction." Genome Research, July 1, 2000. Abstract in RECOMB 2000, Tokyo, April 2000.
