Office, I wouldn't mind. Photoshop, it's got lots of plugins (#1) right?
adobe acrobat, it might as well BE a plugin (#1 again).

That's point #3 and I'd love to known how you got that big. (I guess I should
add a #5: Resource only DLLs.)

I didn't say that aren't common. I said it's a bad idea IMO.

If you ignore system libraries like .NET its self, I'd almost bet that if
you look at it long enough those systems, from a piratical standpoint, are
almost the same as installing dll/so files to be used only by one program.
That is that the average number of programs/applications that depend on any
given file is 1. And as I all ready pointed out, I'll burn disk space to
get the reliability that static linkage gets me.
I seem to recall running into this issue with .NET assemblies and .so files
within the last year.

If the same design runs slower with static linkage than with dynamic linkage,
then there is something wrong with the OS. I can say that with confidence
because everything that a static version needs to do the dynamic version
will also, and then a pile more.
