I'm assuming that by "reliable" you mean trustworthy. In that case, yes, the damn thing just works. The only overall difference between lwip and uip regarding udp is that lwip handles multiple incoming/outgoing packets and (AFAIK) IP fragmentation (which may be relevant if you need to send or receive packets bigger than your interface mtu). The overal capability of handling multiple packets maybe irrelevant depending on the type of tcp and udp applications you intend to run. BTW, uip has simple ip fragmentation but that's more like a hack than a feature, and I don't think you can use that to handle a packet larger than your mtu. - Alexandre
