sender has gone offline
- Easy to send multiple files at once - they're bundled into a zip
file for receivers, with zero compression so extraction is quick
- Can also download individual files out of an uploaded collection
- Sanitises filenames, using sensible non-obnoxious defaults that
should be safe across platforms
- Rudimentary password authentication for uploading files
