Cloud computing is completely useless unless you have a couple of servers that you need to link together. It allows you to share resources while putting unused machines into standby.
Please explain to me how a company, even with 1000 machines used for word processing needs this. Explain to me how even if you need email for these 1000 computers how cloud computing can be useful.
In all fairness one server box running a email client and for file storage is more than enough. And seen as that setup probably covers a good 90% of all business's.
For me and you though at home, if you want to put three or more towers together to make a cloud then good on you. But seen as probably 60% of users on winmx only have one computer, and the other 40 maybe Has a PC and a laptop for the kids. I cant imagine anyone at all every attempting this to run winmx on other than maybe a experiment.
