UCINET does have several tricks for combining graphs in various ways (although I didn't know about some of them until Steve pointed them out!). The sna package for R has a fair number of graph comparison routines, if that's more your interest. These can be used to handle large numbers of graphs at once...Joy Pixley and I analyzed one data set which contained around 1500 networks, for instance. I'm not sure about JUNG, or some of the other tools which are out there....
