IBM announced it will launch its new software, called "Open Client Offering" which is to run on Linux, Microsoft Windows and Apple's Mac OS X. The company states that its new product allows businesses to offer employees a choice of using the same software on Windows and its alternatives. This means that "Open Client Offering" is to cut costs of managing whether to use Linux or Apple relative to Windows. There will be no necessity for companies to pay Microsoft for its licenses for operating systems since the operating systems will no longer rely on software which is Windows-based. One alternative to Microsoft's office document formats is the Open Document Format software, whose development IBM supports. It is going to be used for several tasks like: word processing, presentations, along with collaboration with Lotus Notes, instant messaging and blog tools as well as an Internet Explorer competitor – the Mozilla Firefox web browser. IBM plans to install Open Client on 5% of its desktop PCs. The Linux offering has been made available as the IBM Client for Smart Work product on the Ubuntu and Red Hat Enterprise Linux platforms.
What do you need to pay Microsoft if you use Open Client Offering software?
A: unanswerable

Historical studies reveal that policing agents have undertaken a variety of cross-border police missions for many years (Deflem, 2002). For example, in the 19th century a number of European policing agencies undertook cross-border surveillance because of concerns about anarchist agitators and other political radicals. A notable example of this was the occasional surveillance by Prussian police of Karl Marx during the years he remained resident in London. The interests of public police agencies in cross-border co-operation in the control of political radicalism and ordinary law crime were primarily initiated in Europe, which eventually led to the establishment of Interpol before the Second World War. There are also many interesting examples of cross-border policing under private auspices and by municipal police forces that date back to the 19th century (Nadelmann, 1993). It has been established that modern policing has transgressed national boundaries from time to time almost from its inception. It is also generally agreed that in the post–Cold War era this type of practice became more significant and frequent (Sheptycki, 2000).
What groups did European police work against across borders in the 18th century?
