Multi voice server

Hello. My project is to combine Mumble, TeamSpeak, Ventrillo and Skype into 1 server. What i mean by this is that 1 person connects to the Mumble server and can chat with a person that is connected to the TeamSpeak server. So all the services should be integrated so everyone can talk with each other, but still use their favorite voice client. Example: there are 5 people on Mumble 3 people on TeamSpeak 2 people on Ventrillo 5 people on Skype The people in Mumble will see all the other users as a seperate user, not as 1 user where all their voices will come through. This will be the same way with all the servers. So it will look like there are 15 people on each server. except on skype will it look like there is 16, as we need a bot to host the conversation on skype. You will be paid for every integration you make, you will not get any start money, only money when an integration is done.
