Metadata (5654) Implementation Limits

[I didn't get much response from the imap-protocol list, so I'm trying here, too.]

I'm curious to know what the implementation limits are on servers that support the Metadata extension.  I
would appreciate it if the server authors out there could take a minute to fill out this survey.

I will send a summary to the list once the responses trickle off. (If you want your results to be anonymous,
say so in the comments.)

Thanks,
