Sending REALLY BIG files across the Interweb

I don't think this query in any way requires a back story, but I'll give you a short one just for the hell of it.

My friend and I live far away from eachother right now. We're musicians, and we're attempting to continue collaborating online. We're working with old Garageband project files (a lot of mine are 500-700 MB) and Logic. I have no idea how big the project files for logic are as I don't have it just yet. I can only imagine.

I'm not very good with getting good answers to obscure questions on google, but I'm sure somewhere there exists a simple, intuitive, freeware program or service that will allow us to connect directly and send files between us. However, (like I said I suck at google) all I'm seeing on the first page or two are website services/software asking for me for my god damned money.

Any suggestions? Hints? Riddles?

Jam it back in, in the dark.

Gosh guy, I'm a music nerd. Of course I'm aware of all these websites. I run the download-new-cool-stuff-off-random-strangers-blogs circuit weekly. Let me run some numbers on you.

Rapidshare size-limit: 200 MB, Megaupload size-limit: 250 MB, Sendspace size-limit: 300 MB, Mediafire size-limit 100 MB

So that doesn't help me... I'm talking big, teetering on the edge of a gigabyte type files.

There's nowhere I can't reach.
