I might be wrong in several places, so please correct me if I am.
The Steam version of Oblivion had the main .exe encrypted, so that several mod components / tools (eg. Oblivion Script Extender) could not function with it, thus making it impossible to use a few mods with this version.
1. Will this also be the case in Skyrim?
2. Does someone here has experience with installing mods with the Steam version of Oblivion, and if so, how goes it? Is it harder / easier than with the physical copy? Does one use tools like OMM, or is everything handled from within the Steam application?
i don't know where you got your information from but OBSE works just fine with the Steam installation.
I have around 150+ mods installed, including some that only work with OBSE, such as OBGEv2, ENBSeries Shaders and the major overhaul mods such as OOO, MMM, Frans, FCOM.
The utilities I use are BOSS, Wrye Bash, OBMM, OBSE, Oblivion Crash Prevention System, Fast Exit
There are only two different steps for Steam users
(1) 4GB patch uses the steam version .dll file
(2) When installing Wrye Bash you need use your text editor to correct the default file paths in the bash_default.ini file and save the file as bash.ini
That's all you need to do differently AFAIK
Here is a list of the mods I have running on my Steam installation of Oblivion:
