Jeroman, hit me up on ICQ if you want a demo: 41012160.
As for performance, i think ip-sorter is the fastest on the market at the moment (the only one coded in C).
We ran a test on an empty machine (p3 1.3gig, 512meg ram, scsi disk) and pushed a simulated 5,000,000 hits through the CGI script.
Load average increased from 0.00 to 0.50, with 50% cpu usage.
Its not a 'real-world' benchmark, but it gives you an idea of the peformance. We have traffic brokers doing around 1M/day with no probs.
$300 first copy [including the maxmind $150 premium data], $150 thereafter. (1 copy for 1 server, can be used on all the domains).
Hit me up for a chat if you're interested.
Richard.
