Hello Robert, It sure is...although apparently you find a lot of difference between the largely formal and process/template oriented UP from comparatively informal Agile methods, yes, they share too much in common too. Iterative developement, Continuous integration, test early and often and collaboration are only too obvious. Then take a look at how AUP - Agile Unified Process brings in the Agile Values into UP. The wikipedia has excellent information and links on this!
