You're the first one to ask, so we're a bit in uncharted territories...
Our constraint is that we're sitting on a rather asymmetric 4G connection (the price of living in such a nice landscape...) - we have a decent download speed, but our upload speed is ~100 kbit/s, which makes uploading GB-sized chunks to anywhere a time-consuming and error-prone affair unfortunately - compared with that, burning a data DVD or two or filling a USB stick and mailing the whole lot is more than somewhat faster.
Though if we're doing it scene by scene, it might be more manageable.
If more than a few people are interested, it'd be easiest to manage a password-protected download via my own site - but I'd have to upgrade the package to allow for the required traffic volume - or we'd have to find a 3rd party provider offering such services - so if it's just you, your FTP server looks more attractive.
Let me talk it through with Katharina (co-manager of HakalaFilm) - the rest basically is down to exchanging message and sorting out the details of how much 'shipping' in this particular case amounts to and how precisely we send the data....
(For completeness, I believe I can build an NTSC DVD image at the simple expense of selecting the option - but I gather if you can get the full-res files, you're not overly interested anyway...)
