I use https://www.sharefest.me/ https://www.sharefest.me/ for quick file transfers and it just works with only a web browser. Only downside is Chrome and Firefox don't inter-operate. Not that sure about level of security, but I have a harder time trusting proprietary software over OSS stuff. With sharefest I could even run my own service if I wanted to, all the code is on Github.
