Google Talk for e-learning

Signing up or Google Talk was easy. I have chatted with voice to Martie, Carol, Paul, Sandra and Bessie. I invited many from my address book to Google Talk but they do not have broad band or have another chatting program and were not able to talk with me.
I have had Google Talk open on my desktop this week. What I did like about Google Talk, perhaps the feature was already there with Gmail, was that if anybody sent me an e-mail while I was online, it opened a box on my desktop and I was aware that someone had sent me an e-mail. I also like the fact that a transcript of all texted messages are kept and can be viewed. I have not seen if Conferencing can be done with Google Talk but apparently not.
Could Google Talk be used for e-learning – yes if you do one on one audio work. You could set up a mailing list with Google Group and send the same mail to all students, then deal with them one on one with audio. It is easier to use that the Chat features in WebCT because it is quicker to log in (WebCT takes ages). It does not have the features to share documents found in WebCT but with Google Apps that is and will be possible.
I have a masters student who has broad band and lives far away – we will use Google Talk to talk about his work – he will have his work on his desktop and I will have a copy of the work on my desktop. We will then meaningfully talk about the work, without his travelling and with low telephone costs.
I did like the way all Google applications are linked.
