Hi Jakub, I would not try to solve this on a PHP level. Apart from the fact that it's fairly unreliable to assume a sane maximum (as you noticed, sorry, I am not a PHP deployment specialist), it also means that if your users upload a big file and have to move halfway through or their connection gets cut by other means, they would have to start uploading from scratch.
That is why we implemented file chunking in both the Desktop clients (starting with 1.3.0) and the iOS/Android apps, i.e. we upload files in 10 MB chunks and the server puts them back together. Unfortunately, there is no such patch for the Web client yet, although it would be possible to implement chunking with the introduction of the HTML5 File API (http://caniuse.com/#feat=fileapi) and blobs (http://caniuse.com/#feat=blobbuilder). This would at least work for all browsers that are not IE<=9. You can try the desktop/mobile clients. They should not care as long as the limit is > 10 MB. As for the web client chunking feature, I suggest you either try to implement that yourself, or you could contact ownCloud Inc if you are considering to buying a license.
