Thanks, QBZappy. That's an interesting series of posts.
One question, though. In the first post, you state "Since you can not have the same GTALK acct open on the computer and the OBi, you will need to open a second GTALK acct to receive forked calls.". Is that true? That's basically what I'm asking. Right now, I do have the same account open on the OBi and the computer, with no obvious ill effects. What problems could I experience if I continue using gtalk in such a manner?
