Mininova is running on 4 webservers, 4 database servers, 2 search servers,
one NFS server, and one load balancer (plus 5 additional servers for the forum, blog and the ads).
Its probably a little higher than 5K for servers. But I bet the 5 employees includes the 3 founders, so the overall profit per founder is still fairly high.1 mil - 10-20K for servers/bw - $120K for the 2 employees -10K for misc stuff like office/pens= ~850K
Corp tax rate in netherlands is 25.5% = $633K profit
So if the 3 founders split evenly, each would get €211K euros or $271K dollars. Hardly peanuts, and worth the risk
