Yep. It's fairly common for RPC systems to grow a little shell at some point that lets you arrange objects hierarchically and invoke methods on them. Files then just become objects that support the IFile interface. Mojo had one but it was deleted, and before doing Android the BeOS folks did "OpenBinder" which also had such a shell. There were some attempts at shell-like things in the JVM space as well, I've used CRaSH in the past. There's a lot of scope for interesting OS research here. One issue is that OOP is a bit too dogmatic. Filesystems separate code from data, but OOP is all about fusing them together. If you try and embed an object with an API into the filesystem (e.g. /dev files) then you get stuck when wanting to change the code whilst keeping data constant, which is something that happens all the time with things like image formats, HTML, text files ... operating systems have relatively crude notions of file associations which could be improved a lot.
