They will need to focus on Microsoft's formats for the foreseeable future because of the sheer amount of archaic, but still vitally important, government processes which depend on them.

Once Euro Office gains a significant foothold in those government processes, then they'll have the market power to influence. And, hopefully, force change in Microsoft's behaviour by forcing them to compete against a cheaper and just as capable open product suite.
