Topolyai, if your concern is "the search engine thing" this approach may not be for you. Why? Well, FWIW, what I suggest you do is to build actual unique websites and the only practical way to do that is a shared IP approach. That fact, alone - that each domain resolves to a unique content website - ought to be enough to make any SE happy. If that's not enough then phooey. Build the sites, get the natural type-in traffic to start (that's why you are seeking keyword domains), get some links going (it can happen) and IF, after all that, the SEs still have a problem about your shared IP address then the SE is broken and will eventually be put out to pasture.
