Downloading a large dataset on the web directly into AWS S3 Does anyone know if it's possible to import a large dataset into Amazon S3 from a URL?  

Basically, I want to avoid downloading a huge file and then reuploading it to S3 through the web portal. I just want to supply the download URL to S3 and wait for them to download it to their filesystem. It seems like an easy thing to do, but I just can't find the documentation on it.
Since you obviously posses an AWS account I'd recommend the following:  


Create an EC2 instance (any size)  
Use wget(or curl) to fetch the file(s) to that EC2 instance. For example: wget http://example.com/my_large_file.csv.  
Install s3cmd  
Use s3cmd to upload the file to S3. For example: s3cmd cp my_large_file.csv s3://my.bucket/my_large_file.csv


Since connections made between various AWS services leverage AWS's internal network, uploading from an EC2 instance to S3 is pretty fast. Much faster than uploading it from your own computer. This way allows you to avoid downloading the file to your computer and saving potentially significant time uploading it through the web interface.
