well, the high level interface (get, put, ls, rget, rput, find and glob) is more or less stable. But I am changing the low level interface and the internals of the module to make it mimic as much as possible Perl builtins (read, readline, print, etc). I also want to provide tied interfaces, so that remote files can be used as local ones, transparently.
It would take me a couple of days yet to be able to release a new version.
Could you post the code you have used, where ls and get failed
