[Koha] synchro two instances of Koha

Hi, is it possible to synchronize two (online) instances of Koha? I mean, two identical installations, updated regularly, residing on two different machines, where patrons and administrators can access and modify entries independently. Would it possible to synchronize their databases (and perhaps some relevant external file), on the basis of the modification timestamp of those entries that have been actually modified? (I am not sure whether my question is simply equivalent to that of synchronizing two mysql databases on different servers, for which there might be an answer, if I google it correctly: your advice is appreciated.) Many thanks, Giuseppe.
