You should enter info it requests. The host is host (no slashes), user, pass as needed (make sure N900 doesn't capitalize the user and password, it's darn annoying).

My WM works great, I'm up to 3 (as per screenshot) mounts both here and at the office.

Availability of media will have to wait, transfers are darn slow. Maybe MP3, because video will NOT stream fast enough. With improvements, I'm up to around 100K per second. This is enough to stream audio, but even well=-compressed video is a bit much, especially with jitter and stuff.

Overall, it's a nice thing. I use it to move large amounts of data from the N900 to the PC, as I use mail to move single files that are smaller. I just set MC to copy/move and leave it be.

Your best bet in media over wifi and N900 is streaming. Or a bit more wait until someone takes a look at what is so slow and patches it. Until then, snailsville. Several people said they'll be looking into it, this far limited success.
