Just like anonymous FTP; servers will have timeouts (20 seconds?)
and limits on the number of connections. You could even have a server
that devotes more resources for connections from its own domain.

I've looked around, but haven't seen a complete list of the proposed
required constraints. I imagine a query like
john doe, HOLD, FUZZY, MAXHITS=2
would be about right for incremental search.
Come to think of it, it seems that comma is a bad choice to set off options,
since it is used to set off first names (according to an early document on
the servers). How does one handle people whose first names
are equal to keywords? One of my friends is called Fuzzy; would
smith, fuzzy, FUZZY
find her? Perhaps slashes are less ambiguous:
smith, fuzzy /FUZZY
or does that remind people too much of VMS?
