My station's drive host does his show from Birmingham, through VNC file transfer.
The recent entry about Don Lafontaine and link to an interview with him, explained to me how ISDN allows him to be anywhere, live. We use this to access Niu FM's corporate voice (who is in Wellington) among other things.
The next thing is of course Skype type apps. Google has just launched their Google Talk, and I will either begin using this or Skype soon to run a podcast that has guest hosts, and interviewees live via this app. Considering I already have a Gmail address, the job is already half done.
a) staring at my screen waiting for something to happen, and
b) clicking away - only for Google Talk to hang my computer.
