they don't have to know about any of this: one big command line ready to be copy-pasted that gets the official stable repo.
The point of my rant was to say that: darcs is not universally available on as many computers as CVS is. Even svn sometimes is a bad idea, because it is less widespread than CVS is. Making users download darcs to use slime might be a bit too much (ymmv though)
in my point of view, subversion is out of the scope because it's not a distributed source control system (it's basically cvs rewritten).
Sorry for the misunderstanding, I thought that you wanted the switch to make your use-case easier to support, but apparently you want to convert slime developers to darcs users.
any kind of change in any aspect of life means that you need to leave a local minimum of "energy consumption" in the hope of reaching a better one. it's just like when you learn a new language, but i guess i don't need to go into the details of this particular tought on this particular list... :)
The benefit for developers (some), the pain for users (some). The problem is that one is getting and another one is paying the price.
