Remote control query

Hi,

I've read past posts on remote controls and WinLIRC, but still looking for clear answers that sum it all up. A list of "questions I have":

1. What kinds of RC handset, and IR receiver, (self made or "bought as part of some other kit") can easily be made to work with BSplayer, and/or with other programs in general?
2. What software is needed to handle the IR device, and do such programs learn the signals from the handset or do they come with a database of "known" handset signals that one uses? (WinLIRC is obviously one, I guess?)
3. Do programs need a plugin to be controlled by such a program or how does the IR handling software control the possible media players?
4. Can such programs handle playlists as well as the usual media controls?

If possible, can someone give a "brief summary" how to get a remote control to control BSplayer? (it might be a RC from some existing installed software, or a bare handset+detector, or a handset + a self built detector). Huge detail not needed, but an outline would be extremely useful.

Thanks!
