I have an 800MB file that I need to share to multiple people. I'm guessing ~10,000 will download it.
I purchased extra space on Google Docs. Can Google Docs handle this or should I look into another service?
Here's Google's response: Google Docs size limits.
As long as you upload the file as is (don't convert to Google format) you should be fine with a free account.
You should use BitTorrent as a mean for information dissemination for a file that big of a size to tens of thousands of people.
My suggestion remains the same for a 800MB file.
