The working draft of IPC-2221 revision B will include a Table 4-7 for Lead-Free surface finishes.
Looking at the most recent draft of this table, I see that Immersion Silver is marked as functional, all others are marked as acceptable except OSP, which has a "?" question mark. I don't know what the question mark means because I missed the conference call where this was discussed, but maybe someone out there knows? I thought you would want to hear about this even though it is not set in stone. Currently it is just a working draft and subject to change.
Look near the bottom of the page of this link (which is also subject to change) to see what I mean:
