Well, it's not very easy, in fact, not easy at all. This task will probably require knowledge of PHP and MySQL. You would have to have to have the installations in the same database, but with different table prefixes. To have the data appear in both sides, you would have to either hard code the table prefix in one installation in all the queries for user and user related data. That method would be a PITA to upgrade with. The second, more elegant way, would be to automatically synchronise the user (and user-related) data tables when they update. Then there may be random little bugs lurking around that may wreck the whole thing.
