OK, I once got my son a UK Limited Company as a present for his 13th birthday. He was doing business studies at school, and had to make up some letterheads and business card, so why not do it for real :-) I don't think the business studies teacher appreciated it, which was a shame.
He still has it, and was 18 just in time for the law to change requiring directors to be 18. Phew!
Now I am considering an (early) present for his birthday, but as a fellow geek he may appreciate it. I am thinking of getting him an IPv4 /24 PI, multi homed and routed to his house in Sweden... I have to get it early as RIPE will run out before his actual birthday I expect.
Is this just too geeky as a birthday present I wonder?
