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.

Sending it physically through postage sounds interesting.  I suppose it depends on what those 700mb of data are.  If it's indeed pornography or some form of copyright media, you'd be fine uploading it to any filesharing site or even uploading directly to your destination.  Just remember to encrypt the contents.  Also security through obscurity, name your 700mb of porn something like: "family_photos_07."

For more anonymity, use anonymous proxies.  Go wardriving and piggyback some poor saps wireless router.

If it's something vitally important that you don't want anyone else viewing, physical mail sounds like a plan.  Just hope no one deems it necessary to examine the parcel:  "OH GOSH THIS MAN'S SENDING TERRORIST PLANS/ CHILD PORNOGRAPHY/ COPYRIGHT MEDIA."  Don't use a return address (duh!). 

The most secure way is to transport yourself or a physical proxy (friend) and deliver the contents by hand.
