I noticed the arrival of the memory filesystem and thought I'd look at it. It's early days, and this may all be in work, but I noticed two things:
(1) "providers.xml" hasn't learned about this filesystem yet
(easy to fix with local /META-INF/vfs-providers.xml)
(2) The Commons-VFS "Download" web pages notes an optional
dependency on Commons-Collections (for LRU Cache), but
the RamFileSystem code requires this library.
