Estibot is wrong. I'm not saying its a bad name... but what end user can you sell it to? A company that makes rope? Not sure what your options on development are except for what hpersson mentioned. It does have lots of google results which is good... but in this case I am not sure who would want tied. Reseller mid $xx. For enduser, not sure... not sure who would want it from a corperation standpoint. Good luck with it! I do like it.
