You can upload multi-GB files on YouTube (through regular POST, not flash upload): http://www.youtube.com/my_videos_upload?nobeta

Cheers from the YT team - we hope this can be fixed soon obviously :P

For reference, to make large files:
Linux:
dd if=/dev/zero of=4gbfile bs=1024 count=4194304
Windows:
fsutil file createnew d:\temp\4gbfile.txt 4294967296
