How about "_at_" - I think a leading and trailing underscore will be

Ever seen a MicroSoft AD "SRV" dns query? Try something like:
"_gc._tcp.Default-First-Site._sites.win.ccad.uiowa.edu."
I don't treat anything from Microsoft as a reference implementation.

Havn't seen one that contains leading and trailing underscores, -yet-.
Will the DNS server choke on that? Remember, it only has to be valid
within the scope of a DNS query.
All modern DNS servers will handle it. One of the newer RFCs for
DNS pretty much throws things wide open (can you say UTF-8 and
internationalization?).
...yeah I'd forgotten about that. It looks like the MD5 solution is
probably the most reliable.
