Just weeks after its first public hints of peer-to-peer (P2P) technology aspirations, Sun Microsystems Inc. last week signed an agreement to acquire privately held P2P search company InfraSearch Inc. in Burlingame, Calif. In mid-February, Sun co-founder and Chief Scientist Bill Joy outlined the company's plan to develop a foundational technology for P2P communications called Juxtapose (Jxta). The news came as a surprise to some, because until then, Sun hadn't declared its interest in P2P. With the pending InfraSearch acquisition, however, the company appears to be aggressively trying to position itself for the P2P wave. InfraSearch develops search technology for P2P communications and hence could help provide one of the basic services for Jxta.
