Of course, ml_iPod IS feeware, and it will always be. Neither me nor anybody of the other guys who are contributing to this want to get "paid" for it. It's kind of fun to do it, but it takes a lot of hours and days. Probably you can't even imagine how much time it takes.
that's totally understandable. from personal experience, people generally won't donate unless they're one of the nice set who understand the effort such things do involve. for the large plugins i have which have the donation pages, the main jtfe has been the smallest on the donation stakes (despite it being the most distributed as a gratis item in the winamp distro) so i can understand the frustration on such matters.
however i can understand why people don't donate in the majority of cases seeing as winamp is free, so why not have the plugins be the same. some projects do deserve certain levels of donation and ml_ipod is definitely one of those (especially seeing if people can afford an ipod i'm sure they can afford some sort of donation towards the project - as was definitely the case in the earlier days). the real problem is that too much is placed on people getting renumeration of dev time put in (as seen by some other free plugins changing to shareware/nagware which just doesn't fit in with normal winamp usage).
really the main problem is that with a free player, people expect free add-ons, etc and i think that's just too ingrained into people (well is how i see things to be). thankfully i don't have to make my living on my plugins (otherwise i'd have been homeless a few years back, heh).
frustrating as it maybe, really the best approach to go for is to code for what you want and if you want to then what others want but there's no point in coding something you don't use/need/understand. users demanding stuff is just one of the things that has to be dealt with, and with ml_ipod since the code is available, if it's that much of an issue, you can always inform them of the fact that the code is available and if it's so important to them that they can implement it themselves (usually keeps most of them quiet after that though there's always a few that'll moan more but that's just people for you)
