Short of using a vpn you will need to split the file and upload the chunks to somewhere like Rapidshare. If you have winrar then this is relatively simple, just set winrar to split the file into chunks. In winrar set the file split to Zip 100, this will give you chunks of approx 90 MB, ideal for Rapidshare who's max upload at one go is 100 MB per file. Once split simply upload each chunk to Rapidshare, you can upload again as soon as one upload has finshed:
email the recipient the download details for each chunk as given. Once they have downloaded each part, so long as they have winrar, they only need to open any part and all will automatically re-join.
