This is the help I require. For someone with c#/vb.net/C++ experience that can use the Destinator SDK (for example, and most likely) and build this wrapper.
I already have a module that does TCP/IP communications. The protocol is key/value pair for setting labels, and a string sent from velocity (event) that specifies the target function and parameters.
So the idea is you can write a plug-in in any language, and communicate with velocity via this protocol.
