Basically: it would be nice if projects on the pspdev sdk could employ something similar to Sony's game sharing, so that multiplayer games may be played even if not everyone has the game installed. We can't use Sony's game sharing, so a loader in the form of a homebrew app is needed.

I'll probably try writing this myself, as I'm currently working on a project which will hopefully end up with some form of multiplayer. I'd like to know what features other developers would want in such an application - I can write it to my own needs alone, but then it would only be useful for my own programs, which would be kind of useless.

My current plan is to receive a single archive via wifi, decompress it and execute a preset file inside it. What else would be required?

You can use a concept similar to how the photos are shared via PSPs.
Basically the uploader will search for listeners and broadcast via WIFI a list of apps in /PSP/GAME/

The receiver will run a program that picks up wifi signals and downloads and lists the apps and allows the user to choose which one to install.
When selected, the app will contact the uploader and the uploader will send the whole directory to the receiver (including the duplicate
% directory if for version 1.50 of firmware).

Don't need to autoexecute a file, because maybe the receiver wants
to download multiple apps. Also, it doesn't have to be just aps in
/PSP/GAME/. It can be any music file in /PSP/GAME/ or any video
file in one of those two weird directories, or the PMP files in /PSP/VIDEO/

If you are up to the task you can make a nice tree directory where
the receiver can pick and choose (via checking files) and when done,
select the download button and everything will get downloaded to
the receiver appropriate directory.

And if you have extra time, merge some of the functions into the
firmware (elf but copied as .prx) so that custom firmware allows this
functionality to be built into the XMB so that you can simply choose
download or upload without having to go the XMB/GAME/ directory and
run the uploader or downloader app.

Good luck.
