use gvfs mount points

["Dr. Michael J. Chudobiak" <mjc avtechpulse com>]

Is it normally safe to assume (and choke on a g_assert) that "~/.gvfs" 
mounts are available for non-local-path files (like sftp://whatever...)? 
Or is that bad behaviour?

Is there an elegant way for an app to demand that .gvfs mount points be 
made available? What's best practice here?
