facebook connect mutlsite clarification

hey i was just confused about something

is the facebook connect widget is only available for the main site?

i need a solution where the facebook connect can be available on all the sites. if i use the facebook connect plugin, together with the ultmiate facebook plugin, would there be any conflicts?
i am just testing it. but the permissions that the user ask would be different for both plugins right?

is there any way i can get facebook connect button to appear wherever in multisite?
my client needs in the header of each site and sidebar of each site.

l facebook connect shortcodes and buttons a must for alot of my projects. if i create edublogs kind of sites its not that needed, but if its a normal site, or a normal multisite like e.g. wpmudev.org, then facebook connect shortcodes and widgets would be necessary multisite wide.
