I've added Stream support on Sftp class and intoduced an OutputStreamWrapper at java.io partial namespace. Now it is supprted Get with Tamir.SharpSsh.java.io.OutputStream and System.IO.Stream and Put with Tamir.SharpSsh.java.io.InputStream and also System.IO.Stream. Additional adds based on this implementations are done with byte Arrays (byte[]). Both source files and a compiled release version of Tamir.SharpSSH.dll is available in the attached Zip file. I've named the version 1.1.1.14. Check it out an have fun! ... :)
Source files Sftp.cs, java/io/OutputStreamWrapper.cs and AssemblyInfo.cs
