Talkcast tonight, 7pm PDT/10pm EDT: Macworld/iWorld preview Edition!

All-new dial-in experience! See below -- do not call into Talkshoe, we won't be there. Be sure to set upFuze Meeting before the show if you want to join in live.

Sunday has once again come upon us, and with it comes another TUAW talkcast! There's breaking "news" tonight courtesy of the Wall Street Journal and "people familiar with the matter," suggesting that Apple and Comcast have engaged in talks to deliver an online TV service with special networking arrangements.

We'll discuss that -- but tonight's not just any episode, this one is A Very Special Talkcast. Tonight we have with us a wonderful pair of guests! IDG's Paul Kent, Macworld/iWorld General Manager, has miraculously found an hour in the week before the expo begins to chat with us about the show. Not only is Mister Macworld/iWorld coming by to chat, but we also have a show speaker dropping in: Jean MacDonald, recently of Smile Software, currently of App Camp For Girls, to discuss the App Camp For Girls Open House, happening Saturday morning at Moscone Center.

Whether you're coming to the big show in San Francisco (passes still available!) or not, this is a great opportunity to hear from the source what to expect this year. It should be noted that TUAW's own Steve Sande, Doc Rock, Mike Rose & Victor Agreda Jr. will be roaming the expo halls (not to mention yours truly), so we look forward to meeting many of you in person!

Reminder on new-style talkcasting: With some help from the fine folks at Fuze, we're using a new system to record the show. This should let everyone listen in live -- and, if you want, raise your hand as you would in the Talkshoe room to get unmuted and chime in.

You can join the call in progress (meeting # is 20099010) at 10 pm ET from any computer via this link; if you download the Mac or Windows Fuze clients ahead of time, you'll get better audio and a slicker experience, but browser-only will work fine. Just click the phone icon to join the audio once you're in.

Using an iPhone or iPad? Grab the native clients from the App Store and get busy. (Even Android users can join the party.) Still feel like using the conventional phone dial-in? Just call (201) 479-4595 and enter the meeting number 20099010, then press #.

While the Fuze web and native clients have a chat channel, we'd like to reserve that for host participants, requests to talk and other real-time alerts... so the full-on chat for the show will appear in this very post at 10 pm tonight. You'll need Twitter, Facebook or Chatroll credentials to participate in the chat. We'll remind everyone to check back in at that time.
