Client-side caching?

What is your opinion about implementing  client-side cache, something like that AutoComplete control uses?
In some cases using client-side cache we can avoid multiple validation of same username.

I think it could be beneficial.  It came up a bit near the end of this thread.

Like Joel mentioned, an important concern would be avoiding cached false positives due to a period of user inactivity.  Maybe if we included a lookup timestamp with the cached username, and only reused cached lookups within a ~60 second window?
