First, you would have to do multiple process (forks). Then you have to manage those somehow. Now what do you do if one of the downloads fails - ok the process has to interact with the user. Now another fails. Doh. OK, maybe you can add a "manager process" which will first handle the one then the other. Now, what if the user "aborts" one of the downloads. Do the others continue or are they aborted also? You have to differentiate between being called as part of "fink fetch-all" or "fink fetch-missing", and the case where you are called as part of "fink build" etc. Then, what if two packages try to download the same files (this does actually happen for some packages). So of course you have to handle that as well. Etc. etc. What I want to say with this is not that it's impossible, just not that trivial as you might think at the first glance. I didn't even think about this long (I just started writing the reply by writing what came to my head, so I am certain there are other issues left I didn't even think about). So you first would need to determine what it is actually you want to do (i.e. find answers for my questions above). Once you did this (the hard part), you can think about how to implement it. >(would it be too hard to do for a perl beginner?) Depends on what the beginner knows? I.e. I don't view it as language problem, rather a design issue.
