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....

Hope that helps,
