You are referring to a configuration where OpenSSL uses MS's CryptoAPI
to use the Windows certificate store. Never used it myself, but I see
that TSVN has implemented this, with an extra dialog to select a
client certificate if multiple were found.
I see no reason why that won't work with serf, we probably would have
heard about it if not.

So for Windows there's no problem, only for Mac & Linux we don't have
a smart card solution in 1.8.0 at this time.
