beside the usual issues of cooperating online and people not making backups, it is generally a difficult task to put all files and infos in a single place or into a big monolitic file with a custom frontend.
what i am currently planning for example will on the one hand combine files / installers (only when required) / authorisations (only when required) / and some statistical information about the content - but there is one big problem remaining: alltogether there are still so many bigger files required to make such a bundle complete, that in the end the bundle will be too big.
for quark xpress plug-ins this system is very easy. all of them either just work or ask for a serial, and they sum up to some 100 mb.
but for virtual instruments we´re talking about 5 different authorisation schemes, huge factory content, and endusers which more often only need a single file than the complete bundle so that the size will easily exceed a BD-DL image (not to speak of the 1gb size limit of some hosters or the 2gb limit of most hotline apps)
then there are a few other necessities such as synchronizing the fileserver, my (or other endusers) personal needs - and the fact that the frontend and the file collection is of course something dynamic, where bugfixes, updates and changes will occur from time to time.
in stage 2 i keep in mind the instant DAW project and third party content and see how that can possibly be integrated, too
btw do you know how the prosonic installers look like? where you can either
only intall,
only authorize, or do both - and all with a single click, just in case anyone needs one of these options.
that is how things should look like in a perfect mac world.
even cooler than only making a custom frontend for the installers would be if the user could directly choose to download the files from the online repository like the apple updater controlpanel one did it.
