Without satellite feeds or quicktime streams, coverage for WWDC's keynote address is more difficult to obtain. MacRumors should have Keynote coverage, however.
Options for coverage include:
IRC
a) If you have your own IRC Client, point it to irc.tecknohost.com, #macrumors
b) Download the MacRumors IRC Client which connects you to the proper channel.
d) Web based client can be found at here
Please choose only one option.
Web Coverage
MacRumors will be providing web based coverage. https://www.macrumors.com will redirect to the proper pages as the time approaches.
The WWDC keynote starts at 1pm Eastern time.
