alternate submission service

[jnorell]

Please consider other either alternate or additional methods to submit malware examples, eg. a web based interface.

I run into problems with active mode ftp, where the FTP client supports TLS so any nat/firewall between the client and ftp.rfxn.com can't see what ports should be open for a data connection, and hence the uploads fail.

It's easy enough to edit the ftp commands in files/internals/functions to include a '-p' to enable passive mode, and then my connections work, and I'd be happy to submit such in a pull request. I don't know how universal that option is across the various ftp clients in different OS's.

But would something like a simple web based service be more robust? Maybe try multiple methods until one succeeds.
