We need a fast C++ Usenet client for Windows. It must be able to do the following:
* supply an easy setup wizard (for the user)
* supply an easily customizable GUI (by us, not the user)
* retreive XML data from our webservers and display them appropriately (as we will supply Usenet indices)
* supply easy download wizard based on NZB files (which we will supply)
* extract downloads automatically
* repair downloads automatically based on PAR2 files
Strong Usenet experience and code efficiency is a must.
