It's not really a negative experience. It's just that it can be difficult. In general I think it's useful to think as the bandwidth of a TCP stream being a function of loss and latency (and connection time, at least initially, less of a factor for long lived active connections). The different variants of TCP have slightly different curves. You want your UDP algorithm to play nice with these otherwise you may use more than your fair share or you'll get hammered by competing TCP streams. Apologies if this is kind of basic :)
