Clever.

Right; my point was more or less that the gvfs API needs to expose
enough information such that we can hack this into the file chooser /
other bits if we want such a feature (I think we do). This includes
things like rfile:/// URI's I suppose.

Actually, as mentioned on IRC, TCP/IP transport been in D-Bus for a long
time, it's just not hooked up by default on the session bus nor
forwarded by e.g. ssh yet. You asked about how auth will work; that's a
good question... Havoc, can you shed some light on the D-Bus session bus
forwarding over ssh situation? Thanks!
