We've only got one mac dev, and his ability and desire to work on the port varies. On the plus side, he recently gave it a lot of love, and the source is getting there but not quite ready for you slashdotters to go bang on it :-P If you've got any os x dev skills, drop by the mailing list and lend a hand.

Actually, if you look at the source of the page, you can see that the designers apparently used a flash text image replacement technique for all the "spiffy" ui elements. This is a common technique among some of the most standards-aware web designers today, certainly not an anomaly. The code itself is clean, and if you look at the page without flash, you don't get flash buttons. Just checked it, and the page still looks and works fine with no-script blocking javascript and flash.

AbiCollab (the feature of AbiWord) has a number of backends for you to use in collaboration. One is Jabber-based, one is TCP, and one is the "AbiCollab.net Service" - so you can run it either centrally hosted or peer-to-peer.

Can you simultaneously edit real documents (any document abiword can open, so that's a huge amount and variety), fully featured (every feature AbiWord supports) at the same time - with parties not necessarily looking at the same part of the document (aka, not simple screen-sharing), and so on with those apps? You can with AbiWord. Use it with your voice or voice/video teleconference, sure, but putting a real word-processor in everyone's hands is powerful.

As anonymous posted before, the "plugin" is not a web browser plugin. AbiWord is a regular application. AbiCollab is a recent feature (debuted in 2.6, much improved in 2.8) allowing real-time collaboration between as many people as you want, over a variety of protocols. AbiCollab.net is a new web service that offers remote document storage, history, conversion, etc, that can also produce ".abicollab" files that, when saved and opened by your local copy of AbiWord (which is what happens when you click the edit link on the web), cause AbiWord to join a centrally-hosted collaboration session on that remote document. No browser magic is required: some server magic and abiword local magic takes place, but it's all very streamlined.

Yes - you can "call out" from either your phone access to grandcentral voicemail (call your own number, hit star, type a pin - then hit 2 after a message to call the person back, I think - which will return you to your voicemail when the call is done!) or click a "call" button online which rings the phone of your choice, then your chosen contact. This is the bit they say they might charge for once out of beta, since it's basically like a skype-out (you can add a Gizmo sip address as a line)

Not so - you still need to run this on an x86. It's a virtual machine, not an emulator.
