i just finished writing a new walkhru article on creating a RemObjects SDK for .NET server and matching RemObjects SDK for OSX client. Next go giving a complete overview over that, the article also gives a sneak peak at the ZeroConf support that is coming in RO/.NET (and RO/Delphi, as well) this May, which should be of interest to non-OS X developers, as well!

The article can be found on the wiki.

Enjoy; feedback appreciated!
