There is no such limitation. The biggest XML file I ever stored in ozone was
4.4MB but I didn't encounter any problems with that. Please try to increase the
heap size of the ozone VM. For example: ozone -d<database> -Xmx64000000

So far, only the GLIMS project, which is listed at the ozonies page, found the
time to give us feedback about the usage of ozone in their project.
Are there any new projects?

Indeed!

Yes. ExternalDatabase handles a pool of connections which are assigned to
threads just when this thread actually executes database related code. Note
that this scales much better than JDBC2 connection pooling for example. Ozone
assigns a connection to a thread for _each_single_ request! So for a typical
servlet application that connects a ozone database on a remote host in most
cases no more than 10 actual connections are needed to serve about 100 servlet
threads. All this is completely transparent to the client programmer.
