@Fardilha, we were in the process of updating our blog post on installing MacFusion and were going to suggest using the beta version, but we couldn't get it to mount the remote filesystem, and this was using the latest version of Leopard. On the other hand, the original version of MacFusion works fine for us. We didn't try stacking connections through servers (no way to test that from here) but if we had a need too, I'd bet the original version would work for that as well.

I'm glad to see that someone is still working on MacFusion, it's a great piece of software, and the next time a new beta is released we'll probably give it another go. But for now, we're sticking with the original. Strange that we'd have such opposite experiences, but I guess computers are just like that sometimes. :-)
