What are you guys running in lieu of Dropbox? I have been off in Linux-land for a while, where I got hooked on Dropbox to automatically sync files across multiple systems/OSes. It's been an awesome alternative to emailing myself a bunch of files all the time, especially since it it seamless...just save the file and it's automatically updated on the other computers.
That being said, my dependency on Dropbox over the past couple of years has resulted in most of my work/school documents being stored on the Dropbox server. Because my FreeBSD laptop is the odd man out from several computers capable of running a native client, I'm wondering if there exists a method of staying in sync with the Dropbox server. What tricks do you use? Or is there a cross-platform alternative to the service Dropbox provides?
