DFWC is played offline, each round takes one week and every player's best demo is available for download after the round ends. In case you're asking because you don't have q3/df installed there's gonna be a compilation of the best runs at the end of it(whole dfwc, not after every round) in video format but it doesn't do them justice. They're much better appreciated when you participate, try your best and then sit dumbfounded as you watch how much more skilled and clever the best players are.

edit: so to answer your question, no there won't be a stream
That really sums it up perfectly i remember the first time i participated i had that secret hope to be among the top 5 and such :D later i found the formula.
nLxajA, [bsh]thrasher, Dex may assemble for best demos' reviewing after each round's end. Streamdreamteam probably would need only Shio as a special guest additionally
