I think this is where Seahorse/GnomeKeyring should step in and integration with
it (at least on Linux) makes sense, especially for "system GUI" kind of things
that are everyday on Windows (BaseCSP) and OS X ("unlock keychain" windows).

And it also runs in the kernel [1], speeding up the smart card usage ;)
OpenSC should be portable to the extent of providing portable code for what can
actually be ported between platforms (like PC/SC or OpenSSL). And integrating
with the platform as well as possible should not be forgotten either.
DBus only matters as a platform utility on Linux, elsewhere it is comparable to
"Java runs on anything", whereas in real life you need a compatible JVM to be
available for practical purposes.

There used to be UI functions inside libopensc that were not actually used but
marked the intent of having some kind of UI capabilities.
I would use native and as-thin-as-possible GUI (Whatever Windows API, OS X
Cocoa and GTK and/or Qt for Linux) instead of relying on awkward extras like
assuan or dbus or something similar.
If the internal working of Seahorse requires dbus or if it is a defacto
mechanism on Linux, it cold be used *on Linux* but not for portable code. I
would not use pluggins but keep it simple and provide three different platform
specific implementations.
