Linuxwan,that is actually one of the thousands "Nigerian Scams". This people operate in a similar way. They start getting your attention talking big money,and at the end they always ask you for money to transfer funds ect. (once you send them money via western union,you wont hear from them ever)
Note: A year back i keylogged one of this guys,and changed the passwords of at least 46 email adresses used for those purposes,and you'll be amazed how many people fall for this stuff.
