There are a lot of links to Kifu at GoBase. I believe GoBase was / is a great ressource and should be encouraged, though I don't believe it is best practice for SL to link massively to password protected kifu. Otherwise these are probably the only possible links to some place where at least some people can see them directly. I am not sure how to handle this.

Giving player names, date and if possible tournament / occasion of the game looks most important to me. Anybody able to can look for them himself, the rest is at least less disappointed.
