The best way - get lots of people to try your software out. The way I did was run a couple copies of the client connecting to my own server. Ran the clients on different machines; couldn't be bothered getting them to run from one machine - I assume that this is possible - but I don't know. From memory of the forums there is a way to do it.
I see you got the plugin example to compile under VS2005. I couldn't get that to go so I ended up using VS2003.
