When you start Tor, it will query a Tor directory server to obtain a list of tor nodes. [1] With this node list, Tor will randomly choose node's and exit node's to route traffic through, after some time node's will change which will defeat traffic analysis. > 2) How do you force it to switch IPs at runtime?

I don't know, perhaps someone else on this list can answer this question! > 3) Are there solid Tor alternatives, especially any that incorporate NAT > tunneling, or that provide a more programmatic interface (rather than a > SOCKS/HTTP proxy)? Might not be an alternative, but you could take a look at I2P/gnunet/freenet these are more darknets then anonymizers. Psiphon[2] might be an alternative, but has issues. [3]
