Thanks for your help and I'll try to explain the best I can our process. First of all our branch design is quite theoretical at the moment.
Then yes, every hotfix is RI in the "Patch" branch in its current version (we may have 4 or 5 patch version of a major). When I make a hotfix I can only branch "Patch" from the version to fix. Let say 5.2.3.1 is a hotfix of 5.2.3.0 (this is our non-standard way of versionning), this fix is then RI in "Patch" (which can be in developpement for 5.2.4.0 or further). I'd like to be able to make other fixes with changes of 5.2.3.1 but I can't branch "Patch" from its latest version for obvious reasons.
Our project is based on ASP .NET web forms and consists of several DLL and other ressources. We aren't always sending a complete new setup of the software but it may happen for easy replacement.
