If you are a company who generates promethease.com compatible data, and interested in making it easy for your users to use promethease here is a simple way for you help your users.
Expose the file at some url and then point the user at https://promethease.com/urlimport/ with the url for your data as a parameter. A specific example of this is
https://promethease.com/urlimport/https%3A%2F%2Fs3.amazonaws.com%2Fsnpedia%2FUser%2FDummy%2Fgenome_dummy_phased.vcf
which is the import of
https://s3.amazonaws.com/snpedia/User/Dummy/genome_dummy_phased.vcf
For added security, the data url can be a signed amazon url (or probably just about anything else you might want ).
Besides the general simplicity, this approach able to quickly handle MUCH larger file sizes than would be possible via a user's home connection.
