When you have a Yahoo email account you also have the use of the Yahoo Briefcase that allows 30MB of files to be sent. Goto Yahoo.com and on the home page left side is 'Organize', 'Briefcase', and then login with your Yahoo email login.
You could get some free web space from www.websamba.com and then use wsftple to upload the files you want, and then use it do download to any computer using the FTP utility.
another option would simply be, set up a basic p2p, VPN or just burn the files off onto a dvd-r. you can also get nice little flash drives now that go right up to 4gb
