Sending large amounts of data anonymously

Hello fellow /prog/riders.
I am in need of help.

How do I send large amounts of data (around 700 MB or so, can be larger) totally anonymous to its destination?

I'll be using Tor for two way communications.
But Tor is slow, I do not care that much for packet loss since it's a multimedia stream.
I do require speeds higher than 250 kb/s though.

So, how can I stream my anus porn data while staying Anonymous?

In a few years, IP spoofing will be impossible, I want a long term solution.

>>2 has the right idea, but can be improved.
Write it to magnetic tape, send it by air mail. If it takes two days to get to a given location and you send 10 1-TB tapes per package, you'll have a throughput of nearly 500 Mb/sec.
