The whole Pkcs namespace is only partially implemented - and unlikely to
be useful for most applications. 

Sadly I did not got the time to complete it (originally, before mono
1.0) and it never showed very high into MoMA reports (more recently).

No. Fx 2.0 makes it possible to load a PKCS#12 file, that includes a
certificate and a private key, and the use it with the new APIs. 

So it's not a framework-design problem anymore (like before fx 2.0) but
it's still an application-design problem (in most cases).

No sure if I understand your meaning. Windows tends to "hide" the
private keys (in it's stores) from the users. However there's nothing
you can do, with them, unless you know their "details" (i.e. at least
how to access or use, not necessarily read, it).
