Hi Chanaka, Yes if this does not support upto the level we need it'll be an issue. Did you find any other libraries that are build on top of NIO.
If not we can compare the limitations with common-vfs (will be using commons-net internally for ftp/sftp) on functionality. eg: Unable to modify metadata of a file, Cannot connect via a proxy, etc. If we have enough feature that can be supported with commons-net [1] we can do the inbound-connector with commons-net.
