Generate gzipped Stream of Memorystream

Short:
I'd like to generate a stream (memorystream) containing a gzipped file of a cleartext stream (memorystream, too).

What I did:
I have been using Delphizlib http://gewis.win.tue.nl/info/delphizlib/ for files, but it seems that this is unable to work with streams.

What I want:
I am generating a stream that contains a file (like from memorystream.loadfromfile) and want to compress it. The resulting stream should contain the original file in gzipped form, that I could open as file.gz if I did memorystream.savetofile. However I DON'T want to save it to a file, because I can't guarantee that I have the right to write to any Disk.

Please help.

Where do I find this library and what do I have to put in my uses to use it?
Does it conflict with delphizlib?
Is it possible to do this with delphizlib, too?

My code uses Delphi's ZLib.
If you are using delphi 6 or 7 then you should be having it
I'm not sure whether this is what you need or not.
Please try the code and let me know.

If I can find the library (where?) and the output of CompressStream() is, when saved to a file with tostream.savetofile, readable with winzip, then it is what I need.
