Kinlo, I also thought that the AGPL would require a MySQL module for Eloipool to be made available as source, so I'm wondering if nobody has actually written one or if those that have don't comply with the license. Anyway, if I end up writing one (alternatively I guess a flat file based approach could be more resource friendly...), I'll make sure it gets posted so that people can find it.
Afaik the only pool using authentication with eloipool is Triplemining, and we don't use mysql for that.
Wasn't aware that Slush's algorithm is hoppable - the impression I got from reading about the various methods was that it is specifically designed to prevent that. But it's quite possible that I missed something there. Do you happen to have any details?
Slush's method was indeed specifically designed to prevent hopping. The Titanic was specifically designed to be used for many, many years on sea. Unfortunately things don't always play out the way one hoped. You should read and understand
meni's excellent document about poolhopping.
