Thanks, wj, for your praise and Lobster for your offer.
But for the moment KSMAS should mature a little bit more, before being used as I mention before (integrated to sites, etc), but that would be great if it was done someday.
I wondered if WDZ would be willing to try it out in a mid-future, as I'm not on many other forums and can't personally test it in real life (many users, overload, session-migration, etc.).
Obviously I can understand that he neither wants some code he doesn't know himself nor wants to test anything unstable or exploitable on his board.
So well, I'll have to work some more on it (like making the
nifty installer work again
) and improving some other things that are probably more prioritary than this.
Edit: Well, it's not that much load, it's hardly more than 300kB which have to be exported. And it has been doing fine until I did some changes for supporting safe mode (installing from an assistant.php running under Apache's UID). That has been working in very limited areas, so I'm trying to merge it with the old setup style and let it automatically switch to either one after collecting some info about the browser.
The tarball method could be interesting for the images I have base64 encoded, as they get bigger when stored as text.
But yeah, I should reconsider some things about the setup.
