Wow I finally found this amazing software.. I spent months looking for something like that, but no luck. But suddenly I faced this tiny (~36kb with installer) program and tried it.

It is only useful for people who have several network interfaces and have to deal with routing all the time. I use WiFi and LAN, I use virtual network interfaces (VPN) and always wanted to make some programs work with one interface, some programs work with different one. Like - browsing with one, downloading with second, ICQ with different and all at the same time. Windows routing abilities (route program) helps but it is a pain to keep routing table updated.

ForceBindIP does exactly it has to, you can use it to launch using particular netword interface. It is fast, small, free and it works, really great who has to handle multiple NICs.
